Jeremiah 3:8-9
8
I saw, when, for this very cause that backsliding Israel had committed adultery, I had put her away and given her a bill of divorce, yet treacherous Judah, her sister, didn't fear; but she also went and played the prostitute.
9
It happened through the lightness of her prostitution, that the land was polluted, and she committed adultery with stones and with stocks.
