What Languages Was the Bible Written In?

Hebrew, Aramaic, and Greek across the biblical world

In 2014, during a public meeting in Jerusalem, Israeli Prime Minister Benjamin Netanyahu told Pope Francis that Jesus had walked this land and spoken Hebrew. Pope Francis replied, “Aramaic.” Netanyahu then added that Jesus also knew Hebrew. The exchange was brief, but it captured something important: the linguistic world of the Bible was multilingual, and the language Jesus most likely used in everyday life was not the language in which the canonical Gospels were preserved.

The Bible was written across many centuries in several linguistic settings. Most of the Hebrew Bible is in Hebrew; portions of Ezra and Daniel and a few shorter passages are in Aramaic; and the books of the New Testament are preserved in Koine Greek. Some books included in Catholic and Orthodox Old Testaments also survive in Greek, which makes the full picture more complex than the simple formula “Old Testament Hebrew, New Testament Greek.” This guide explains where each language appears, why those languages mattered, what Jesus likely spoke, and what all of this means for Christians reading the Bible in translation today. For the broader structure of Scripture, see What Is the Bible? A Complete Christian Guide.

Three Main Languages of the Bible

The principal languages of the biblical books are Hebrew, Aramaic, and Koine Greek. Each belongs to a different part of the historical world in which Scripture took shape. Hebrew is the dominant language of the Hebrew Bible. Aramaic appears in portions of the Old Testament and became a major spoken and administrative language across the Near East. Koine Greek became a widely shared language throughout the eastern Mediterranean and is the language in which the New Testament has come down to us.

The transitions between these languages were not the result of one Church decision or one historical event. They reflect centuries of political change, exile, migration, trade, imperial administration, and cultural contact. The geography matters too: the linguistic environment of the lands of the Bible was never uniform. Judea, Galilee, Egypt, Syria, Asia Minor, Greece, and Rome all belonged to different linguistic environments even when people moved constantly between them.

There is also one important qualification. When Christians say that the Old Testament was written in Hebrew and Aramaic, they are usually describing the books of the Hebrew Bible and the Old Testament shared by Protestants. Some writings included in Catholic and Orthodox Old Testaments are preserved in Greek, while the textual histories of several deuterocanonical books are more complicated. The history of the Septuagint and other ancient Greek Jewish Scriptures is therefore part of the language story as well.

Hebrew: The Main Language of the Hebrew Bible

Biblical Hebrew is the language of most of the Hebrew Bible. It belongs to the Northwest Semitic branch of languages and is closely related to languages such as Phoenician and Moabite. Ancient Hebrew manuscripts were written primarily with consonants. The vowel signs familiar from many printed Hebrew Bibles were added much later by Jewish scholars known as the Masoretes, who worked during the early medieval period to preserve pronunciation, reading traditions, and textual detail.

Biblical Hebrew was not completely uniform across the centuries represented by the biblical texts. Vocabulary, grammar, and style vary from book to book and period to period. Some poetic passages preserve linguistic features often regarded as archaic, while post-exilic writings can show later developments and stronger contact with Aramaic. Scholars continue to debate exactly how particular linguistic features should be dated, so it is better to think of Biblical Hebrew as a historical range of related forms rather than one frozen version of the language.

The relationship between ancient Hebrew and modern Hebrew is similarly one of continuity and change. Modern Hebrew preserves a great deal of ancient vocabulary and structure, but it is not simply Biblical Hebrew spoken again without development. Centuries of Jewish literary use, rabbinic Hebrew, medieval Hebrew, contact with other languages, and the modern revival all shaped the language spoken in Israel today.

The Aramaic Portions of the Old Testament

A smaller but historically important part of the Hebrew Bible is written in Aramaic, another Northwest Semitic language closely related to Hebrew. Aramaic became a major language of diplomacy and administration across the ancient Near East and was especially important under the Neo-Assyrian, Babylonian, and Persian empires.

The principal biblical Aramaic passages are Ezra 4:8–6:18 and 7:12–26, Daniel 2:4b–7:28, Jeremiah 10:11, and the Aramaic expression in Genesis 31:47. Aramaic also appears in names, expressions, and later Jewish interpretive traditions beyond these passages.

In Ezra, the Aramaic sections include imperial correspondence and documents connected with Persian administration. Daniel shifts from Hebrew into Aramaic at Daniel 2:4b and remains in Aramaic through chapter 7 before returning to Hebrew. These passages reflect a world in which Hebrew and Aramaic could exist side by side rather than one language simply replacing the other overnight.

That point is important. Older popular accounts sometimes describe Aramaic as having straightforwardly displaced Hebrew after the Babylonian exile. The evidence is more complicated. Aramaic became extremely important as a spoken and administrative language, but Hebrew continued to be written and spoken in different forms during the Second Temple period. The Jewish population of first-century Judea and Galilee lived in a genuinely multilingual environment.

What Language Did Jesus Speak?

Most scholars regard Aramaic as the strongest candidate for Jesus' primary everyday language, particularly in Galilee. The Gospels preserve several Aramaic expressions associated with Jesus, including talitha koum in Mark 5:41 and ephphatha in Mark 7:34. The cry from the cross preserved in Matthew 27:46 and Mark 15:34 also reflects a Semitic form of Psalm 22:1, though the exact linguistic form differs between the two Gospel accounts.

Jesus also lived within a Jewish culture in which Hebrew remained important for Scripture, worship, learning, and identity. Luke 4:16–20 describes Jesus reading from a scroll of Isaiah in the synagogue at Nazareth. Luke does not explicitly state the language of that particular scroll, so the passage should not be used as proof by itself that Jesus read Hebrew aloud on that occasion. Taken together with the broader Jewish linguistic evidence, however, some knowledge of Hebrew is entirely plausible.

Knowledge of Greek is possible as well. Greek was widely used in the eastern Roman Empire, and Galilee was connected to Greek-speaking commercial and administrative networks. How fluently Jesus himself spoke Greek remains debated, and the Gospels do not allow us to measure his proficiency with confidence. It is therefore safer to say that Jesus probably lived in a multilingual environment than to assign him a precise modern-style language profile.

The villages associated most closely with his life and ministry, including Capernaum, belonged to this mixed linguistic world. Aramaic was probably central to ordinary speech; Hebrew remained important in Jewish religious life; and Greek circulated more widely through the region than a simple “Aramaic-only Galilee” picture would suggest.

One further distinction matters. The surviving canonical Gospels do not preserve long stretches of Jesus' teaching as Aramaic discourse. They preserve his sayings in Greek, while occasionally retaining individual Aramaic words or phrases. That is different from claiming that none of his words survive in the language he spoke: the preserved Aramaic expressions are precisely the exceptions that make the linguistic history so interesting.

Koine Greek and the New Testament

The books of the New Testament are preserved in Koine Greek, the widely used form of Greek that developed after the conquests of Alexander the Great and remained enormously important throughout the eastern Mediterranean under Roman rule. “Koine” means “common,” reflecting a broadly shared form of Greek that could cross many regional boundaries.

This does not mean every New Testament author wrote in the same style. Luke and Hebrews, for example, often use more polished literary Greek than Mark or Revelation. Semitic influence also appears in New Testament vocabulary, syntax, names, quotations, and turns of phrase. The result is not a single uniform “Bible Greek” but a collection of authors writing Greek in different ways within a multilingual Jewish and Greco-Roman world.

Greek was particularly useful for the early Christian movement because it could circulate far beyond Aramaic-speaking Judea and Galilee. Jewish communities throughout the Mediterranean had already been reading Scripture in Greek for generations. The ancient Greek translations of Jewish Scripture therefore formed part of the linguistic world in which the New Testament authors wrote and quoted Scripture.

Greek should not be described as the only possible language in which early Christians could have written. Aramaic-speaking Christian communities certainly existed, and other Christian languages emerged as the movement spread. But for texts intended to circulate among communities across places such as Antioch, Ephesus, Corinth, and Rome, Koine Greek offered an unusually broad readership.

From Spoken Aramaic to Written Greek

The difference between Jesus' probable everyday language and the language of the Gospels is one of the most important linguistic facts in New Testament study. Jesus' teaching was delivered within an Aramaic-speaking Jewish setting, yet the canonical Gospels are Greek compositions. That means many sayings attributed to Jesus reached written form through a process that included memory, oral transmission, interpretation, and translation across languages.

Scholars have long asked whether particular Greek expressions in the Gospels preserve traces of underlying Aramaic phrasing. Sometimes a Semitic idiom may plausibly stand behind the Greek. But reconstructing the exact Aramaic wording of an individual saying is usually uncertain. There is no surviving Aramaic transcript of the Sermon on the Mount or the parables against which the Greek can simply be checked.

The Gospels themselves also have different compositional histories. Luke explicitly says that earlier accounts existed and that traditions had been handed down by people associated with the events, but he does not say that he personally interviewed every eyewitness. Modern scholarship also debates the literary relationships among Matthew, Mark, and Luke. For the broader question of how the four canonical accounts were composed and related to one another, see What Are the Gospels and Why Do They Matter?

The movement from spoken tradition to written manuscript also belongs to the larger story of how the Bible was written and preserved. Language and manuscript transmission are connected, but they are not the same question: one asks what language a text was composed or transmitted in; the other asks how physical copies survived and were compared.

What This Means for Reading a Translation Today

Most Christians encounter Scripture through translation. Modern Bible translations are generally produced from scholarly editions of the Hebrew, Aramaic, and Greek texts, while also consulting ancient manuscript evidence and early translations where the wording is uncertain. Different Christian traditions may use somewhat different Old Testament textual bases or canonical collections, but translators ordinarily work from the ancient-language evidence rather than simply translating a modern Bible from another modern language.

Translation inevitably requires judgment because languages do not correspond word for word. A Hebrew term may carry a range of associations that no single English word captures. Greek grammar can express relationships that sound unnatural if reproduced literally. An Aramaic expression may have cultural resonance that disappears when rendered in another language. Translators therefore make choices about precision, readability, literary form, idiom, and ambiguity.

That does not make translation arbitrary. Serious translations are produced by scholars who compare manuscripts, grammar, vocabulary, ancient usage, literary context, and the history of interpretation. Where the underlying text or translation is genuinely uncertain, many modern editions signal the issue in footnotes rather than pretending that no question exists.

For readers, knowing the Bible's linguistic history can make comparison between translations more useful. A difference between two English Bibles does not automatically indicate a corrupted text or a theological agenda; often it reflects two defensible ways of translating an ancient expression. At the same time, significant differences deserve attention rather than being dismissed. A good study Bible, commentary, or interlinear resource can show where Hebrew, Aramaic, or Greek helps explain why translators made different choices.
