He spoke in a third language which was used in the writing of some books of the Hebrew Bible. It was written from approximately the 1660s to the 400s B.C. The fact that Jesus Christ and the disciples all knew and spoke Greek, as a "third language," in addition to Aramaic and Hebrew, is also indicated and supported by the fact that all the gospels and epistles of the New Testament are written and preserved in the Greek language. The designation "Old Testament" places this part of the canon in relation to the New Testament, the part of the Bible canonical only to Christians. 'seventy'; often abbreviated 70; in Roman numerals, LXX), is the earliest extant Koine Greek translation of books from the Hebrew Bible, various biblical apocrypha, and deuterocanonical books. The Book of Isaiah (Hebrew: ספר ישעיהו, IPA: [sɛ.fɛr jə.ʃaʕ.ˈjɑː.hu]) is the first of the Latter Prophets in the Hebrew Bible and the first of the Major Prophets in the Christian Old Testament.

The truth is, most of the books of the Bible were written in Hebrew or Greek. The Old Testament was mainly written in Biblical Hebrew, with some portions (notably in Daniel and Ezra) in Biblical Aramaic. In the Old Testament, 39 of the 46 books were originally written in Hebrew (with some portions written in Aramaic). The very first translation of the Hebrew Bible was into Greek. This work took in the 39 canonical books of the Old Testament as well as some books written after Malachi and before the New Testament. Contents of the Septuagint The Septuagint includes the 39 canonical books of the Old Testament . The Greek Old Testament, or Septuagint (from the Latin: septuāgintā, lit.

The Old Testament, as originally inspired, was divided into three major divisions. 7 other books, called the deuterocanonicals (Tobit, Judith, Wisdom, Sirach, Baruch, and First and Second Maccabees.) The Septuagint was written in koine (common) Greek, the everyday language used by Jews in dealing with Gentiles. Nearly all of the Old Testament is written in Hebrew and the language of the New Testament is Koine, a form of Greek that was widely understood in the Mediterranean 2,000 years ago. The first division was the Law, the second was the Prophets, and the third was the Writings (which included the Psalms and Proverbs). However, neither of these two languages was Jesus’ mother tongue. As Jews dispersed from Israel over the years, they forgot how to read Hebrew but could read Greek, the common language of the day. Apart from two short passages, (Genesis 31:47 and Jeremiah 10:11) Ezra 4:8-6:18; 7:12-26; and Daniel 2:4-7:28 are the portions of the Old Testament that are written in Aramaic.The rationale for the two sections of Ezra that are in Aramaic is easy to determine. The Christian Old Testament, Protestant version, contains all the same books as the Jewish Bible. Instead, it was written in three different languages—Hebrew, Aramaic, and Greek. A few parts are written in Aramaic, a language that uses the same alphabet as Hebrew, but is slightly different. The Old Testament was mostly written in Hebrew. were written in Greek.
