Job 22:22 - Ellicott's Commentary On The Whole Bible

The law from his mouth. — It would be highly interesting to know whether by this law (Torah), the Law, the Torah, was in any way alluded to. One is naturally disposed to think that since Job seems to be the one Gentile book of the Old Testament, the one book in which the literature of Israel touches the world at large, it must, therefore, be prior to the Law, or else have been written in independence and ignorance of it. The former seems by far the more reasonable supposition, and certainly the life depicted appears to be that of the patriarchal times before the giving of the Law. And yet, on the other hand, it is hard to know what could be meant by “His words” prior to the Mosaic Revelation, unless, indeed, the expression is a witness to the consciousness of that inner revelation of the voice of God in the conscience which the holy in all ages have never wanted.
