John Wesley on Exodus 32:6

And they rose up early on the morrow, and offered sacrifice to this new made deity. And the people sat down to eat and drink of the remainder of what was sacrificed, and then rose up to play - To play the fool, to play the wanton. It was strange that any of the people, especially so great a number of them, should do such a thing. Had they not, but the other day, 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? - Yet They made a calf in Horeb, the very place where the law was given It was especially strange that Aaron should be so deeply concerned, should make the calf and proclaim the feast! Is this Aaron the saint of the Lord! Is this he that had not only seen, but had been employed in summoning the plagues of Egypt, and the judgments executed upon the gods of the Egyptians? What! And yet himself copying out the abandoned idolatries of Egypt? How true is it, that the law made them priests which had infirmity, and needed first to offer for their own sins?
