What is his name? It is not at all clear why Moses should suppose that the Israelites would ask him this question, nor does it even appear that they did ask it. Perhaps, however, he thought that, as the Egyptians used the word "god," generically, and had a special name for each particular god—as Ammon, Phthah, Ra, Mentu, Her, Osiris, and the like—when he told his people of "the God of their fathers," they would conclude that he, too, had a proper name, and would wish to know it.
The Egyptians set much store by the names of their gods, which in every ease had a meaning. Ammen was "the concealed (god)," Phthah, "the revealer," Ra,"the swift," etc. Hitherto Israel's God had had no name that could be called a proper name more than any other.
He had been known as "El," "The High;" "Shad-dai," "The Strong;" and "Jehovah," "The Existent;" but these terms had all been felt to be descriptive epithets, and none of them had passed as yet into a proper name.
What was done at this time, by the authority of God himself, was to select from among the epithets one to be distinctly a proper name, and at the same time to explain its true meaning as something more than "The Existent"—as really "The Alone Existent"—the source of all existence.
Henceforth this name, which had previously been but little used and perhaps less understood, predominated over every other, was cherished by the Jews themselves as a sacred treasure, and recognised by those around them as the proper appellation of the one and only God whom the Israelites worshipped.
It is found in this sense on the Moabite stone, in the fragments of Philo-Byblius, and elsewhere.
