(be-REET ye-shah-NAH) n. “Old Testament” is the Christian term for the Jewish Scriptures. The word “testament” comes from the Latin word for will (as in last will and testament) and derives from the Greek word diatheke, which means covenant. The translators chose the word “testament” because God's covenant (like a will) is unilateral. The term comes from 2 Corinthians 3:14, where Rav Sha'ul refers to the old covenant. Note: It is better to use the acronym Tanakh among practitioners of Judaism and “former covenant” among Messianic believers.
