'Astray' in the Bible

“Speak to the Israelites and say to them, ‘If any man’s wife goes astray (deviates) and is unfaithful to him,

Then the priest shall have her take an oath and say to the woman, “If no man has lain with you and if you have not gone astray into uncleanness [while married], then be immune to this water of bitterness that brings a curse;

but if you have gone astray [while married] and you have defiled yourself and a man other than your husband has been intimate with you”
