'Adultery' in the Bible

I saw that even though I had sent unfaithful Israel away for all her adulteries and had given her a divorce decree, her treacherous sister Judah didn't fear, and she, too, committed adultery.

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

Why should I forgive you? Your sons have forsaken me, and you have sworn by those who aren't gods. When I gave them enough food to satisfy them, they committed adultery and marched to the prostitute's house.

Will you steal, murder, commit adultery, swear by false gods, burn incense to Baal, follow other gods that you don't know,

Among the prophets of Jerusalem I saw a horrible thing, for they commit adultery and live a lie. They strengthen the hands of those who do evil, so that no one repents of his evil. All of them are like Sodom to me, and her residents like Gomorrah."

because they did something stupid in Israel. They committed adultery with their neighbors' wives, and in my name they spoke lies that I didn't command them. I'm the one who knows, and I'm a witness," declares the LORD.'"
