Deuteronomy 23:22-24
Context23:22 If you refrain from making a vow, it will not be sinful. 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. 23:24 When you enter the vineyard of your neighbor you may eat as many grapes as you please, 1 but you must not take away any in a container. 2
