32:1-6 While Moses was in the mount, receiving the law from God, the people made a tumultuous address to Aaron. This giddy multitude were weary of waiting for the return of Moses. Weariness in waiting betrays to many temptations. The Lord must be waited for till he comes, and waited for though he tarry. Let their readiness to part with their ear-rings to make an idol, shame our niggardliness in the service of the true God. They did not draw back on account of the cost of their idolatry; and shall we grudge the expenses of religion? Aaron produced the shape of an ox or calf, giving it some finish with a graving tool. They offered sacrifice to this idol. Having set up an image before them, and so changed the truth of God into a lie, their sacrifices were abomination. Had they not, only a few days before, in this very place, heard the voice of the Lord God speaking to them out of the midst of the fire, Thou shalt not make to thyself any graven image? Had they not themselves solemnly entered into covenant with God, that they would do all he had said to them, and would be obedient? ch. 24:7. Yet before they stirred from the place where this covenant had been solemnly made, they brake an express command, in defiance of an express threatening. It plainly shows, that the law was no more able to make holy, than it was to justify; by it is the knowledge of sin, but not the cure of sin. Aaron was set apart by the Divine appointment to the office of the priesthood; but he, who had once shamed himself so far as to build an altar to a golden calf, must own himself unworthy of the honour of attending at the altar of God, and indebted to free grace alone for it. Thus pride and boasting were silenced.

4. fashioned it with a graving tool, after he had made it a molten calf—The words are transposed, and the rendering should be, "he framed with a graving tool the image to be made, and having poured the liquid gold into the mould, he made it a molten calf." It is not said whether it was of life size, whether it was of solid gold or merely a wooden frame covered with plates of gold. This idol seems to have been the god Apis, the chief deity of the Egyptians, worshipped at Memphis under the form of a live ox, three years old. It was distinguished by a triangular white spot on its forehead and other peculiar marks. Images of it in the form of a whole ox, or of a calf's head on the end of a pole, were very common; and it makes a great figure on the monuments where it is represented in the van of all processions, as borne aloft on men's shoulders.

they said, These be thy gods, O Israel, which brought thee up out of the land of Egypt—It is inconceivable that they, who but a few weeks before had witnessed such amazing demonstrations of the true God, could have suddenly sunk to such a pitch of infatuation and brutish stupidity, as to imagine that human art or hands could make a god that should go before them. But it must be borne in mind, that though by election and in name they were the people of God, they were as yet, in feelings and associations, in habits and tastes, little, if at all different, from Egyptians. They meant the calf to be an image, a visible sign or symbol of Jehovah, so that their sin consisted not in a breach of the FIRST [Ex 20:3], but of the SECOND commandment [Ex 20:4-6].
