The prophet closes with the same warning: Take heed. Be on your guard against such treachery. To do this involves two very important considerations: knowing and agreeing with the plan of the covenant God has made for the people of God, and knowing and agreeing with what God has planned for the marriage. To fulfill the first, one must be committed to worshiping and serving God in holiness and righteousness. To fulfill the second, one must know that the marriage is a covenant confirmed by God and the wife is a lifelong partner.
