Hosea 3:2

Hosea obeyed the Lord and sought out his wife. He had to pay 15 shekels of silver and an homer and a half of barley (about 9 bushels) since she had apparently become the property of someone else. Fifteen shekels of silver was half the price of a dead slave (Exodus 21:32), and barley was cattle food. An homer and a half cost about 15 shekels of silver. [Note: Wolff, p. 61.] So Hosea evidently paid the price of a dead slave for his wife.
