Deuteronomy 9:21

21 And your sin which ye had made, the calf, I took, and burnt it with fire, and pounded it and ground it down till it became fine; and it became like dust, and I cast the dust into the brook that descended from the mountain.

Deuteronomy 9:21 Meaning and Commentary

Deuteronomy 9:21

And I took your sin, the calf which ye had made
Which was the object of their sin, which lay in making and worshipping it; see ( Isaiah 31:7 )

and burnt it with fire, and stamped it;
with his feet after it was burnt, to bring it into small pieces:

and ground it very small;
or, as the Targum of Jonathan,

``ground it in a mortar well;''

the burnt and broken pieces:

even until it was as small as dust;
being ground to powder, as in ( Exodus 32:20 )

and I cast the dust thereof into the brook that descended out of the
mount;
and made the children of Israel to drink of it, as in the previously mentioned place; (See Gill on Exodus 32:2); all this was done before the prayer for Aaron and the people.

Deuteronomy 9:21 In-Context

19 And I was greatly terrified because of the wrath and anger, because the Lord was provoked with you utterly to destroy you; yet the Lord hearkened to me at this time also.
20 And he was angry with Aaron to destroy him utterly, and I prayed for Aaron also at that time.
21 And your sin which ye had made, the calf, I took, and burnt it with fire, and pounded it and ground it down till it became fine; and it became like dust, and I cast the dust into the brook that descended from the mountain.
22 Also in the burning, and in the temptation, and at the graves of lust, ye provoked the Lord.
23 And when the Lord sent you forth from Cades Barne, saying, Go up and inherit the land which I give to you, then ye disobeyed the word of the Lord your God, and believed him not, and hearkened not to his voice.
