'Whoredom' in the Bible

Because of the thoughtlessness of Israel’s prostitution [her immorality mattered little to her], she desecrated the land and committed adultery with [idols of] stones and trees.

When the Lord first spoke through Hosea, the Lord said to him, “Go, take for yourself a wife of prostitution and have children of [her] prostitution; for the land commits great acts of prostitution by not following the Lord.”
