Here, I. Orders are given to Gideon to begin his government with the reformation of his father's house, v. 25, 26. A correspondence being settled between God and Gideon, by the appearance of the angel to him, it was kept up in another way; the same night after he had seen God, when he was full of thoughts concerning what had passed, which probably he had not yet communicated to any, The Lord said unto him in a dream, Do so and so. Note, God's visits, if gratefully received, shall be graciously repeated. Bid God welcome, and he will come again. Gideon is appointed, 1. To throw down Baal's altar, which it seems his father had, either for his own house or perhaps for the whole town. See the power of God's grace, that he could raise up a reformer, and the condescensions of his grace, that he would raise up a deliverer, out of the family of one that was a ring-leader in idolatry. But Gideon must not now think it enough not to worship at that altar, which we charitably hope he had not done, but he must throw it down; not consecrate the same altar to God (it is bishop Hall's observation), but utterly demolish it. God first commands down the monuments of superstition, and then enjoins his own service. He must likewise cut down the grove that was by it, the plantation of young trees, designed to beautify the place. The learned bishop Patrick, by the grove, understands the image in the grove, probably the image of Ashtaroth (for the word for a grove is Ashereh), which stood upon or close by the altar. 2. To erect an altar to God, to Jehovah his God, which probably was to be notified by an inscription upon the altar to that purport—to Jehovah, Gideon's God, or Israel's. It would have been an improper thing for him to build an altar, even to the God of Israel, especially for burnt-offering and sacrifice, and would have been construed into a contempt of the altar at Shiloh, if God, who has not tied up himself to his own laws, had not bidden him to do it. But now it was his duty and honour to be thus employed. God directs him to the place where he should build it, on the top of the rock, perhaps in the same place in which the angel had appeared to him, near to the altar he had already built: and he must not do it in a hurry, but with the decency that became a religious action (in an orderly manner, as it is in the margin), according to the ancient law for altars raised on particular occasions, that they must be of earth not of hewn stone. The word here used for the rock on which the altar was to be built signifies a fortress, or strong-hold, erected, some think, to secure them from the Midianites; if so, it was no security while the altar of Baal was so near it, but it was effectually fortified when an altar to the Lord was built on the top of it, for that is the best defence upon our glory. On this altar, (1.) He was to offer sacrifice. Two bullocks he must offer: his father's young bullock, and the second bullock of seven years old, so it should rather be read, not even the second as we read it. The former, we may suppose, he was to offer for himself, the latter for the sins of the people whom he was to deliver. It was requisite he should thus make peace with God, before he made war on Midian. Till sin be pardoned through the great sacrifice, no good is to be expected. These bullocks, it is supposed, were intended for sacrifices on the altar of Baal, but were now converted to a better use. Thus, when the strong man armed is overcome and dispossessed, the stronger than he divides the spoil, seizes that for himself which was prepared for Baal. Let him come whose right it is, and give it to him. (2.) Ball's grove, or image, or whatever it was that was the sanctity or beauty of his altar, must not only be burnt, but must be used as fuel for God's altar, to signify not only that whatever sets up itself in opposition to God shall be destroyed, but that the justice of God will be glorified in its destruction. God ordered Gideon to do this, [1.] To try his zeal for religion, which it was necessary he should give proofs of before he took the field, to give proof of his valour there. [2.] That some steps might hereby to taken towards Israel's reformation, which must prepare the way for their deliverance. Sin, the cause, must be taken away, else how should the trouble, which was but the effect, come to an end? And it might be hoped that this example of Gideon's, who was now shortly to appear so great a man, would be followed by the rest of the cities and tribes, and the destruction of this one altar of Baal would be the destruction of many.
