Hosea 3:1-2

Then the LORD said to me, “Go again, love a woman (Gomer) who is beloved by her husband and yet is an adulteress, even as the LORD loves the children of Israel, though they turn to other gods and love the raisin cakes [used in the feasts in pagan worship].” So I bought her for myself for fifteen pieces of silver and a homer and a half of barley [the price of a common slave].
