If thou meet thine enemy's ox or his ass going astray, thou shalt certainly bring it back to him.

If they have sinned against thee, (for there is no man that sinneth not,) and thou be angry with them, and give them up to the enemy, and they have carried them away captives unto the enemy's land, far or near;

But Amaziah would not hear; for it was of God, that he might deliver them into the enemy's hand, because they had sought after the gods of Edom.
