Exodus 32:17-27

17 And Josue hearing the noise of the people shouting, said to Moses: The noise of battle is heard in the camp.
18 But he answered: It is not the cry of men encouraging to fight, nor the shout of men compelling to flee: but I hear the voice of singers.
19 And when he came nigh to the camp, he saw the calf, and the dances: and being very angry, he threw the tables out of his hand, and broke them at the foot of the mount:
20 And laying hold of the calf which they had made, he burnt it, and beat it to powder, which he strewed into water, and gave thereof to the children of Israel to drink.
21 And he said to Aaron: What has this people done to thee, that thou shouldst bring upon them a most heinous sin?
22 And he answered him: Let not my lord be offended; for thou knowest this people, that they are prone to evil.
23 They said to me: make us gods, that may go before us; for as to this Moses, who brought us forth out of the land of Egypt, we know not what is befallen him.
24 And I said to them: Which of you hath any gold? and they took and brought it to me; and I cast it into the fire, and this calf came out.
25 And when Moses saw that the people were naked, (for Aaron had stripped them by occasion of the shame of the filth, and had set them naked among their enemies)
26 Then standing in the gate of the camp, he said: If any man be on the Lord’s side, let him join with me. And all the sons of Levi gathered themselves together unto him:
27 And he said to them: Thus saith the Lord God of Israel: Put every man his sword upon his thigh: go, and return from gate to gate through the midst of the camp, and let every man kill his brother, and friend, and neighbour.
