Deuteronomy 9:16

And I looked
When he was come down from the mount, and was nigh the camp:

and, behold, ye had sinned against the Lord your God;
that plainly appeared by what they had done, and at which he was amazed; and therefore a behold is prefixed to it, it being such a gross sin, having so much impiety and ingratitude, and stupidity in it:

and made you a molten calf;
that he saw with his eyes, and them dancing about it; see ( Exodus 32:19 )

ye had turned aside quickly out of the way which the Lord had commanded
you;
see ( Deuteronomy 9:7 ) .
