Deuteronomy 23:17-25

17No Israelite man or woman must ever become a prostitute at places where people worship their gods.

18You must not bring the money that people pay to these prostitutes into the Lord's temple. Do not use it to offer a gift that you have promised to the Lord your God. He hates prostitutes, both men and women.

19You may lend money or food or anything else to another Israelite. But do not ask him to give you back more than you lent to him.

20You can ask a foreign person to pay back more, but not an Israelite. If you obey this command, the Lord your God will bless you. When you live in your new land, God will bless everything that you do.

21If you promise to give something to the Lord your God, be careful to bring your gift soon. If you do not bring it, that is a sin. The Lord will certainly demand it from you.

22You may choose not to promise any gift. That is not a sin.

23But whatever you promise to do, you must be careful to do it. If you choose to promise a gift to the Lord your God, give it soon.

24If you go into your neighbour's vineyard, you may eat some of the grapes. You may eat as many grapes as you want, but do not carry any away in a basket.

25If you go into your neighbour's field of grain, you may eat some of it. You may pick some grain with your hands, but do not use a knife to cut it down.
