Canaan, the language of

mentioned in Isa. 19:18, denotes the language spoken by the Jews
resident in Israel. 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 Canaanite schools, and the clay tablets of
Babylonian literature were stored in the Canaanite libraries.
Even the Babylonian divinities were borrowed by the Canaanites.
