New Testament from WikiPedia:

The common languages spoken by both Jews and Gentiles in the Holy Land at the time of Jesus were Aramaic, Koine Greek, and to a limited extent a colloquial dialect of Mishnaic Hebrew. It is generally believed that the original text of the New Testament was written in Koine Greek, the vernacular dialect in 1st century Roman provinces of the Eastern Mediterranean, and later translated into other languages, most notably, Latin, Syriac, and Coptic. However, some of the Church Fathers[citation needed] seem to imply that Matthew was originally written in Hebrew or Aramaic, and there is another contention[citation needed] that the author of the Epistle to the Hebrews wrote in Hebrew, which was translated into Greek by Luke. Neither view holds much support among contemporary scholars[citation needed], who argue that the literary facets of Matthew and Hebrews suggest that they were composed directly in Greek, rather than being translated, a view known as Greek primacy.
