'Fornication' in the Bible

"For long ago I broke your yoke and tore off your bonds, But you said, "I won't serve you!' Instead, on every high hill and under every green tree, you bend down to commit fornication.

"When a man divorces his wife, she leaves him and becomes another man's wife, will the first husband return to her again? The land would be deeply polluted, would it not? Since you have committed fornication with many lovers, would you now return to me?" declares the LORD.

"Look up to the barren heights and see. Is there any place where you have not been ravished? You have sat beside the road, waiting for them like a nomad in the desert. And you have polluted the land with your fornication and your wickedness.

In the time of King Josiah the LORD told me, "Have you seen what unfaithful Israel did? She went up on every high hill and under every green tree, and she committed fornication there.

She took her fornication so lightly that she polluted the land and committed adultery with stones and trees.
