Ezekiel 22:15-16

The Lord promised (1) to scatter the people of Jerusalem among the other nations and to disperse them in other lands. He would (2) refine their sinful practices away. Some commentators claimed that after the exile idolatry was no longer a temptation for the Israelites. [Note: E.g., Cooper, p. 231; and Fisch, p. 155.] They would (3) not be able to maintain their holiness in exile, and the nations would regard them as unclean. Then they would know that Yahweh was the only true God. This was His primary purpose in judging them.
