21 When you shall vow a vow unto the LORD your God, you shall not delay to pay it: for the LORD your God will surely require it of you; and it would be sin to you.
22 But if you shall abstain to vow, it shall be no sin to you.
23 That which is gone out from your lips you shall keep and perform; even a freewill offering, according as you have vowed unto the LORD your God, which you have promised with your mouth.
24 When you come into your neighbor's vineyard, then you may eat your fill of grapes at your own pleasure; but you shall not put any in your vessel.
25 When you come into the standing grain of your neighbor, then you may pluck the heads with your hand; but you shall not move a sickle unto your neighbor's standing grain.
