1. A solemn appeal to God concerning it, with which they begin their defence, intending thereby to give glory to God first, and then to give satisfaction to their brethren, v. 22. (1.) A profound awe and reverence of God are expressed in the form of their appeal: The Lord God of gods, the Lord God of gods, he knows. Or, as it might be read somewhat closer to the original, The God of gods, Jehovah, the God of gods, Jehovah, he knows, which bespeaks his self-existence and self-sufficiency; he is Jehovah, and has sovereignty and supremacy over all beings and powers whatsoever, even those that are called gods, or that are worshipped. This brief confession of their faith would help to obviate and remove their brethren's suspicion of them, as if they intended to desert the God of Israel, and worship other gods: how could those entertain such a thought who believed him to be God over all? Let us learn hence always to speak of God with reverence and seriousness, and to mention his name with a solemn pause. Those who make their appeals to heaven with a slight, careless, "God knows," have reason to fear lest they take his name in vain, for it is very unlike this appeal. (2.) It is a great confidence of their own integrity which they express in the matter of their appeal. They refer the controversy to the God of gods, whose judgment, we are sure, is according to truth, such as the guilty have reason to dread and the upright to rejoice in. "If it be in rebellion or transgression that we have built this altar, to confront the altar of the Lord at Shiloh, to make a party, or to set up any new gods or worships," [1.] "He knows it (v. 22), for he is perfectly acquainted with the thoughts and intents of the heart, and particularly with all inclinations to idolatry (Ps. xliv. 20, 21); this is in a particular manner before him. We believe he knows it, and we cannot by any arts conceal it from him." [2.] "Let him require it, as we know he will, for he is a jealous God." Nothing but a clear conscience would have thus imprecated divine justice to avenge the rebellion if there had been any. Note, First, In every thing we do in religion, it highly concerns us to approve ourselves to God in our integrity therein, remembering that he knows the heart. Secondly, When we fall under the censures of men, it is very comfortable to be able with a humble confidence to appeal to God concerning our sincerity. See 1 Cor. iv. 3, 4.
