15 And Moses turned and went down from the mountain, [with] the two tables of the testimony in his hand—tables written on both their sides: on this side and on that were they written.

Matthew Henry's Commentary on Exodus 32:15

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.
