Exodus 32:16

And the tables were the work of God, and the writing was the writing of God, graven upon the tables.

The tables were the work of God, and the writing was the writing of God. It has been alleged that this phraseology is according to the Hebrew idiom, in which the mountains of God mean high mountains, etc.; and so nothing more is meant by the language used here than to give an idea of the surpassing beauty and finished execution of these written tables. But it is not within the compass of language to declare more explicitly that the engraving was miraculously accomplished. The meaning undoubtedly is, that the law was inscribed on these two tables without the agency of angels or any other creature, by the immediate operation of God.
