Литература Второго Храма к Бамидбар 12:7

[204] Some have said, that it was inappropriate for Him to swear; for an oath is added to assist faith, and only God and one who is God’s friend is faithful, even as Moses is said to have been found “faithful in all His house” (Numb. 12:7). Moreover, the very words of God are oaths and laws of God and most sacred ordinances; and a proof of His sure strength is that whatever He saith cometh to pass, and this is specially characteristic of an oath. It would seem to be a corollary from this that all God’s words are oaths receiving confirmation by accomplishment in act.

[228] So then it is best to trust God and not our dim reasonings and insecure conjectures: “Abraham believed God and was held to be righteous” (Gen. 15:6); and the precedence which Moses takes is testified to by the words he is “faithful in all My house” (Numb. 12:7). But if we repose our trust in our own reasonings, we shall construct and build up the city of Mind that corrupts the truth: for “Sihon” means “corrupting.”
