22. But if thou shalt indeed obey. He moderates the terror with which He had inspired them for two reasons, — first, that He may rather gently attract them than force them by the fear of punishment; secondly, lest, if they imagine that the Angel is formidable to them, the anxiety conceived in their minds should deaden their perception of His mercy and layout. Now, although I postpone to another place the promises whereby their obedience to the Law was confirmed, I have thought it right to include this among the exhortations or eulogiums whereby the dignity of the Law is enhanced, because it relates to the time past, for thus is the expression to be paraphrased, “Take heed that ye respond to God who deals so liberally with you. The promises which He made to your fathers as to the inheritance of the land, He is now ready to perform, unless your iniquity should stand in the way. Make room, then, for His grace, that, by the hand of the Angel, He may lead you into His rest.” In order to stimulate them still more, He points out to them their need of His aid, as though He had said that nothing, could be more miserable than their case, unless they were protected from so many enemies by His defense, for He enumerates several most important nations to which they would be by no means a match unless they should fight under the guidance of the Angel. He says, therefore, that if they only obey His Law, there is no occasion for them to be afraid, for that He will destroy by His own power alone all that shall rise against them to resist them.
