'Committed Adultery' in the Bible

For when ye have stolen, murdered, committed adultery and penury; When ye have offered unto Baal, following strange and unknown gods;

namely, that they have broken their wedlock, and stained their hands with blood: yea even with their idols have they committed adultery, and offered them their own children to be devoured, whom they have born unto me.

Do not thou triumph, O Israel; make no boasting more than the Heathen. For thou hast committed adultery against thy God: strange rewards hast thou loved, more than all the corn floors.

But I say unto you, That whosoever looketh on a wife lusting after her, hath committed adultery with her already in his heart.
