And here we may call to mind, that Caiaphas, in his day, was such an one as Isaac, combining the prophet and the priest in his own person. And Caiaphas would fain have abused his office and his gift to his own wretched purposes and desires. He delivered a true prophecy with a design on the life of the Lord Jesus. John xi. And in earlier days, the prophet Balaam was of the same generation. He sought, all he could, to use his gift in the service of his lusts. God, however, took him out of his own hand, and forced his lips to utter the sentence of righteousness, the judgment of truth. And, though it be sad to put such men together, even in a single action, yet so it is; for such was Isaac in Gen. xxvii. Though a sanctified and filled vessel, he would have served the wish of his own fond heart, in the use of the treasure which he carried; but God took him out of his own hand, and used him as the oracle of His settled, sovereign purpose. Again I say, it is sad thus to link such men as Isaac and Balaam in a common moral action. But we know that "that which is born of the flesh is flesh." As an old writer says, "The water that is foul in the well will not be clean in the bucket." The flesh in an Isaac is as the flesh in a Balaam; and the world in the heart of each of them is the same world. But they are not one _to the end_. This is the comfort, the gracious comfort, of which I spoke before. Balaam is Balaam still, the man who loved the wages of unrighteousness, and ran greedily after his own error for reward; he goes on as Balaam, giving counsel to Balak to cast a stumbling-block before the people of God; and at last he fell, as Balaam, with the uncircumcised, slain with the sword, like those that go down to the pit. But Isaac repented with godly sorrow unto a repentance not to be repented of. When his eye is opened, and he discovers what he had been about, and how Jacob had got the blessing which he had prepared for Esau--when it thus confronts him to the face, that he had been withstanding God, but that he could not prevail, his soul seems to awaken as from sleep, and to get alive to all this, for we read of him, that he trembled with a great trembling greatly. v. 33. The sight, the moral sense, of the place that he was filling, startles his soul. He trembles in himself. The flesh which he had been nourishing could not stand him in such a moment--and he seeks it not--it has been exposed to him; and in the light and energy of the better life, he acts according to faith, and says, speaking now of Jacob, and no longer of Esau, "I have blessed him, yea, and he shall be blessed."
