'Committed Adultery' in the Bible

I observed that it was because unfaithful Israel had committed adultery that I had sent her away and had given her a certificate of divorce. Nevertheless, her treacherous sister Judah was not afraid but also went and prostituted herself.

Indifferent to her prostitution, she defiled the land and committed adultery with stones and trees.

Why should I forgive you?Your children have abandoned Meand sworn by those who are not gods.I satisfied their needs, yet they committed adultery;they gashed themselves at the prostitute’s house.
