Having brought in God as coming to judgment with them, he now gives an account of the process and of the sentence of the Judge, whose words are contained in this and the following verses. I will testify against thee; I will plead with thee, and declare my charge or indictment against thee. Even thy God; not only in general, as thou art my creature, but in a special manner, by many singular favours and obligations, and by that solemn covenant made at Sinai; whereby I avouched thee to be my peculiar people, and thou didst avouch me to be thy God, Deuteronomy 26:17,18.
