Exd 32:21 And Moses said unto Aaron, What did this people unto thee, that thou hast brought so great a sin upon them? Exd 32:22 And Aaron said, Let not the anger of my lord wax hot: thou knowest the people, that they [are set] on mischief. Now we got Aaron, doing what Moses did earlier up on the mountain with the Lord...note worthy Aaron is calling Moses 'my lord'...

Also notice that Moses is now calling the people..."this people"

they ain't belonging to anybody at this point! Don't nobody want to own them!
Exd 32:23 For they said unto me, Make us gods, which shall go before us: for [as for] this Moses, the man that brought us up out of the land of Egypt, we wot not what is become of him. Now we have Aaron reminding Moses that he brought this people and lead them ...sounding familiar
