'Unfaithfully' in the Bible

"Speak to the Israelites and tell them, 'If any man's wife goes astray and behaves unfaithfully toward him,

When he has made her drink the water, then, if she has defiled herself and behaved unfaithfully toward her husband, the water that brings a curse will enter her to produce bitterness -- her abdomen will swell, her thigh will fall away, and the woman will become a curse among her people.

We have prepared and consecrated all the items that King Ahaz removed during his reign when he acted unfaithfully. They are in front of the altar of the Lord."

Please recall the word you commanded your servant Moses: 'If you act unfaithfully, I will scatter you among the nations.

I will make the land desolate because they have acted unfaithfully, declares the sovereign Lord."

"You are righteous, O Lord, but we are humiliated this day -- the people of Judah and the inhabitants of Jerusalem and all Israel, both near and far away in all the countries in which you have scattered them, because they have behaved unfaithfully toward you.
