'Unfaithfully' in the Bible

"Speak to the {Israelites}: 'When a man or woman {commits} any of the sins of humankind by acting unfaithfully, [it is] a sin against Yahweh, and that person will be guilty;

"Speak to the {Israelites} and say to them, 'If any man's wife goes astray and acts unfaithfully to him,

When he has made her drink the waters, it will come about, if she has defiled herself and acted unfaithfully to her husband and the waters of bitterness that bring a curse go into her and her stomach swells and her hip falls away, the woman will be as a curse in the midst of her people.
