Gemara is generally considered to be a conclusive commentary and hermeneutic of Mishnah made by Jewish scholars called Amoraim. The word gemara is traced to the Aramaic as meaning to learn. This word is gamar (גמר) in the Hebrew, which means to complete or conclude. Some believe that this is a more accurate view of the meaning of Gemara. This word is used several times in scripture.

Mizemor (Psalm) 138:8YHVH will perfect that which concerns me. Thy mercy, O YHVH endures forever; forsake not the works of thine own hands.

Ezera (Ezra) 7:12Artaxerx'es, king of kings, unto Ezera, the priest, the scribe, even a scribe of the words of the law, of the God of heaven, perfect peace, and so forth.

Shalom Alecheim!
