Deuteronomy 23:20-25

20 To a stranger thou mayest lend in usury, and to thy brother thou dost not lend in usury, so that Jehovah thy God doth bless thee in every putting forth of thy hand on the land whither thou goest in to possess it.
21 `When thou vowest a vow to Jehovah thy God, thou dost not delay to complete it; for Jehovah thy God doth certainly require it from thee, and it hath been in thee -- sin
22 `And when thou forbearest to vow, it is not in thee a sin.
23 The produce of thy lips thou dost keep, and hast done [it], as thou hast vowed to Jehovah thy God; a free-will-offering, which thou hast spoken with thy mouth.
24 `When thou comest in unto the vineyard of thy neighbour, then thou hast eaten grapes, according to thy desire, thy sufficiency; but into thy vessel thou dost not put [any].
25 When thou comest in among the standing-corn of thy neighbour, then thou hast plucked the ears with thy hand, but a sickle thou dost not wave over the standing-corn of thy neighbour.
