When the lepers arrived at the outskirts of the encampment, they entered one tent and ate and drank. Then they carried off from there some silver, gold, and clothes, and went out and hid them. After this, they returned, entered another tent, raided it, and went and hid all of that, too!

And he put an end to the false priests, who had been put in their positions by the kings of Judah to see to the burning of offerings in the high places in the towns of Judah and the outskirts of Jerusalem, and all those who made offerings to Baal and to the sun and the moon and the twelve signs and all the stars of heaven.
