Exodus 32:25-27

Amplified Bible, Classic Edition

²⁵ And when Moses saw that the people were unruly and unrestrained (for Aaron had let them get out of control, so that they were a derision and object of shame among their enemies),

²⁶ Then Moses stood in the gate of the camp, and said, Whoever is on the Lord’s side, let him come to me. And all the Levites [the priestly tribe] gathered together to him.

²⁷ And he said to them, Thus says the Lord God of Israel, Every man put his sword on his side and go in and out from gate to gate throughout the camp and slay every man his brother, and every man his companion, and every man his neighbor.
