Deuteronomy 9:20 Meaning and Commentary

Deuteronomy 9:20

And the Lord was very angry with Aaron, to have destroyed him,
&c.] For complying with the request of the people in making a calf for them, and for that miserable shift he made to excuse himself; which so provoked the Lord, that he threatened to destroy him, and he was in danger of being cut off, had it not been for the intercession of Moses:

and I prayed for Aaron also the same time:
who either was included in the general prayer for the people, ( Exodus 32:31 ) or a particular prayer was made for him, though not recorded, and which also succeeded.
