'Partner' in the Bible

she who forsakes the partner of her youth and has forgotten the covenant of her God,

He who robs his father and his mother and says, "There is no crime," is partner to a man who corrupts.

Being a partner with a thief is hating one's life; a curse he will hear, but not disclose.

But you ask, "{For what reason}?" Because Yahweh stands as a witness between you and the wife of your youth, against whom you have been unfaithful, even though she [is] your marriage partner and {your wife by covenant}.
