20. But when I shall have brought them. In other words, God again enlarges upon the atrociousness of their iniquity, in that, when He had dealt liberally with the Israelites, they would turn His benefits into occasions of perversity, since nothing can be more base than such ingratitude, he says, then, that He will perform to them, unworthy as they are, that which he has sworn, so that He might thus be faithful to His promises. He commends the fertility of the land, since this striking pledge of His indulgence should have attracted them by its sweetness to love so beneficent a Father in return. Hence, therefore, the perverseness of their nature is demonstrated, inasmuch as, when full, they would kick against Him, like horses which become intractable from high feeding. But, after having complained of their future rebellion, He again says, that when they shall have been brought into sore straits, and overwhelmed with miseries, this song would be “as a witness,” as if they should proclaim in it their own condemnation.
When He says that He knew their disposition, (244) or what they forged within them, (for the word employed is יצר, yetzer, which is equivalent to figment, or imagination, and includes all the thoughts and feelings,) it is apparent that He was by no means unaware how in He was bestowing His benefits upon such unworthy persons, but that He thus contended with their unworthiness, in order that His goodness might be the more conspicuous; and also that He desired this instruction to be set before them, ungodly and hopeless as they were, which He knew they would despise, so as to render them all the more inexcusable by this test. But it may be objected, Why then did He not turn their hearts to better things? for thus do ungodly railers allow themselves to dispute with Him; but let us rather reflect on the words of Paul, “Nay but, O man, who art thou that repliest against God? Hath not the potter power over the clay, to make” of it vessels according to his own will? (Romans 9:20.) And,
“Who hath first given to him, and it shall be recompensed unto him again?” ( Romans 11:35.)
So will it come to pass, that we shall exclaim with trembling, Oh, how deep are the judgments of God; how incomprehensible are His ways!
That God should judge from their former life what they would be hereafter, does not seem very logical; but these two clauses are to be taken connectedly, that God foresees that nothing else is to be expected from them, but that they would be carried away into sin by their unbridled lust; and secondly, that it had already been sufficiently manifested by their many iniquities how desperate was their obstinacy.
