“For Moses had said, Consecrate yourselves to day to the LORD, even every man upon his son, and upon his brother; that he may bestow upon you a blessing this day.”
King James Version (KJV)
32:27 Slay every man his brother - That is, Slay all those that you know to have been active for the making and worshipping of the golden calf, though they were your nearest relations or dearest friends. Yet it should seem they were to slay those only whom they found abroad in the street of the camp; for it might be hoped that those who were retired into their tents were ashamed of what they had done.
32:28 And there fell of the people that day about three thousand men - Probably these were but few in comparison with the many that were guilty; but these were the men that headed the rebellion, and were therefore picked out to be made examples of; for terror to others.
32:31 Oh, this people have sinned a great sin - God had first told him of it, #Ex 32:7|, and now he tells God of it by way of lamentation. He doth not call them God's people, he knew they were unworthy to be called so, but this people. This treacherous ungrateful people, they have made them gods of gold.
