EASTON’S BIBLE DICTIONARY (1897 EDITION)
Canaan, the language of – mentioned in Isa. 19:18, denotes the language spoken by the Jews resident in Palestine.
The language of the Canaanites and of the Hebrews was substantially the same.
This is seen from the fragments of the Phoenician language which still survive, which show the closest analogy to the Hebrew.
Yet the subject of the language of the “Canaanites” is very obscure.
The cuneiform writing of Babylon, as well as the Babylonian language, was taught in the Canaanitish schools, and the clay tablets of Babylonian literature were stored in the Canaanitish libraries.
Even the Babylonian divinities were borrowed by the Canaanites.
