Leviticus 10:20 - Ellicott's Commentary On The Whole Bible

And... he was content. — He acknowledged Aaron’s plea to be just, and that he had himself spoken hastily. This is a remarkable instance of Moses’ humility, and of the human side of his nature as a lawgiver. (See also Numbers 32:6, &c.) Hence Jewish tradition from time immemorial ascribes the mistake to Moses, and not to Aaron. The paraphrase of this verse in the Palestine Chaldee Version, which embodies the ancient opinions, is very instructive. It is as follows: “And when Moses heard it, he approved of this explanation. Whereupon he sent a herald through the whole camp of Israel, saying, It is I from whom the law had been hid, and my brother Aaron brought it to my remembrance.”
