Deuteronomy 23:16-25

16Indeed, he may live among you in any place he chooses, in whichever of your villages he prefers; you must not oppress him.

17There must never be a sacred prostitute among the young women of Israel nor a sacred male prostitute among the young men of Israel.

18You must never bring the pay of a female prostitute or the wage of a male prostitute into the temple of the Lord your God in fulfillment of any vow, for both of these are abhorrent to the Lord your God.

19You must not charge interest on a loan to your fellow Israelite, whether on money, food, or anything else that has been loaned with interest.

20You may lend with interest to a foreigner, but not to your fellow Israelite; if you keep this command the Lord your God will bless you in all you undertake in the land you are about to enter to possess.

21When you make a vow to the Lord your God you must not delay in fulfilling it, for otherwise he will surely hold you accountable as a sinner.

22If you refrain from making a vow, it will not be sinful.

23Whatever 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.

24When you enter the vineyard of your neighbor you may eat as many grapes as you please, but you must not take away any in a container.

25When you go into the ripe grain fields of your neighbor you may pluck off the kernels with your hand, but you must not use a sickle on your neighbor’s ripe grain.
