Deuteronomy 23:23-25

Living Bible

²³ Once you make the vow, you must be careful to do as you have said, for it was your own choice, and you have vowed to the Lord your God.

²⁴ “You may eat your fill of the grapes from another man’s vineyard, but do not take any away in a container. ²⁵ It is the same with someone else’s grain—you may eat a few handfuls of it, but don’t use a sickle.
