Matthew Poole and continuators on Exodus 32:2

2 And Aaron said unto them, Break off the golden ear-rings which are in the ears of your wives , of your sons, and of your daughters, and bring them unto me.

Which were of good value and common use among the Eastern people who seem to have used them superstitiously, Gen. 35. 4. Iudg. 8. 24. and therefore Aaron demands these partly that he might take away one vice or occasion of vice, whilest the people were intent upon another, and partly that the proposed loss of their precious ear-rings might cool their idolatrous desires,

Whom he thought most fond of their jewels and most unlikely to part with them.
