Deuteronomy 23:16-25

16Let them live among you wherever they like and in whatever town they choose. Do not oppress them.

17No Israelite man or woman is to become a shrine prostitute.

18You must not bring the earnings of a female prostitute or of a male prostitute into the house of the Lord your God to pay any vow, because the Lord your God detests them both.

19Do not charge a fellow Israelite interest, whether on money or food or anything else that may earn interest.

20You may charge a foreigner interest, but not a fellow Israelite, so that the Lord your God may bless you in everything you put your hand to in the land you are entering to possess.

21If you make a vow to the Lord your God, do not be slow to pay it, for the Lord your God will certainly demand it of you and you will be guilty of sin.

22But if you refrain from making a vow, you will not be guilty.

23Whatever your lips utter you must be sure to do, because you made your vow freely to the Lord your God with your own mouth.

24If you enter your neighbor’s vineyard, you may eat all the grapes you want, but do not put any in your basket.

25If you enter your neighbor’s grainfield, you may pick kernels with your hands, but you must not put a sickle to their standing grain.
