'Adultery' in the Bible

who commits adultery, preferring a stranger over her husband!

I'll judge you with the same standards by which I issue verdicts against a woman who commits adultery and murder. I'll avenge the blood you've shed with impassioned wrath.

because they've committed adultery, and blood covers their hands. They've also committed adultery with their idols, making their sons born to me to pass through the fire as an offering to them.
