Bible: Deuteronomy 23:21, 23

23:21 When you make a vow to the Lord your God you must not delay in fulfilling it, for otherwise he 1  will surely 2  hold you accountable as a sinner. 3  23:23 Whatever you vow, you must be careful to do what you have promised, such as what you have vowed to the Lord your God as a freewill offering.
