18 And he said, It is not the sound of a shout of victory, neither is it the sound of a shout of defeat: it is the noise of alternate singing I hear.

Matthew Henry's Commentary on Exodus 32:18

Commentary on Exodus 32:15-20

(Read Exodus 32:15-20)

What a change it is, to come down from the mount of communion with God, to converse with a wicked world. In God we see nothing but what is pure and pleasing; in the world nothing but what is sinful and provoking. That it might appear an idol is nothing in the world, Moses ground the calf to dust. Mixing this powder with their drink, signified that the backslider in heart should be filled with his own ways.
