Exodus 32:22

And Aaron said, let not the anger of my lord wax hot
He addresses him in a very respectful manner, though his younger brother, being in a superior office, the chief ruler of the people, king in Jeshurun; and he perceived a violent emotion rising in him, great indignation in his countenance, and an high resentment of what was done, and therefore he entreats his patience to hear him, in a few words, what he had to say, and he begins with the well known character of the people:

thou knowest the people, that they [are] set on mischief;
or are "in wickedness" ^F17; wholly in it, and under the power and influence of it, given up to it, and bent upon it; and there was no restraining them from it; and he appeals to the knowledge of Moses himself for the truth of this, of which their several murmurings against him, since they came out of Egypt, were a proof; see ( 1 John 5:19 ) .
