Genesis 15:16

16. The iniquity of the Amorites is not yet full. The reason here given is deemed absurd, as seeming to imply that the sons of Abram could not otherwise be saved, than by the destruction of others. I answer, that we must with modesty and humility yield to the secret counsel of God. Since he had given that land to the Amorites, to be inhabited by them in perpetuity, he intimates, that he will not, without just cause, transfer the possession of it to others; as if he would say, ‘I grant the dominion of this land to thy seed without injury to any one. The land, at present, is occupied by its lawful possessors, to whom I delivered it. Until, therefore, they shall have deserved, by their sins, to be rightfully expelled, the dominion of it sill not come to thy posterity.’ Thus God teaches him that the land must be evacuated, in order that it may lie open to new inhabitants. And this passage is remarkable, as showing, that the abodes of men are so distributed in the world, that the Lord will preserve quiet people, each in their several stations, till they cast themselves out by their own wickedness. For by polluting the place of their habitation, they in a certain sense tear away the boundaries fixed by the hand of God, which would otherwise have remained immovable. Moreover, the Lord here commends his own longsuffering. Even then the Amorites had become unworthy to occupy the land, yet the Lord not only bore with them for a short time, but granted them four centuries for repentance. And hence it appears, that he does not, without reason, so frequently declare how slow he is to anger. But the more graciously he waits for men, if, at length, instead of repenting they remain obstinate, the more severely does he avenge such great ingratitude. Therefore Paul says, that they who indulge themselves in sin, while the goodness and clemency of God invite them to repentance, heap up for themselves a treasure of wrath, (Romans 2:4;) and thus they reap no advantage from delay, seeing that the severity of the punishment is doubled; just as it happened to the Amorites, whom, at length, the Lord commanded to be so entirely cut off, that not even infants were spared. Therefore when we hear that God out of heaven is silently waiting until iniquities shall fill up their measure; let us know, that this is no time for torpor, but rather let every one of us stir himself up, that we may be beforehand with the celestial judgment. It was formerly said by a heathen, that the anger of God proceeds with a slow step to avenge itself, but that it compensates for its tardiness by the severity of its punishment. Hence there is no reason why reprobates should flatter themselves, when he seems to let them pass unobserved, since he does not so repose in heaven, as to cease to be the Judge of the world; nor will he be unmindful of the execution of his office, in due time. We infer, however, from the words of Moses, that though space for repentance is given to the reprobate, they are still devoted to destruction. Some take the word עון (ayon) for punishment, as if it had been said that punishment was not yet matured for them. But the former exposition is more suitable; namely, that they will set no bound to their wickedness, until they bring upon themselves final destruction.
