Deuteronomy 23:24 ASV

²²  But if thou shalt forbear to vow, it shall be no sin in thee.

²³  That which is gone out of thy lips thou shalt observe and do; according as thou hast vowed unto Jehovah thy God, a freewill-offering, which thou hast promised with thy mouth.

²⁴  When thou comest into thy neighbor's vineyard, then thou mayest eat of grapes thy fill at thine own pleasure; but thou shalt not put any in thy vessel.

²⁵  When thou comest into thy neighbor's standing grain, then thou mayest pluck the ears with thy hand; but thou shalt not move a sickle unto thy neighbor's standing grain.
