22 If you are not willing to make a promise, then it shall be without sin.
23 But as soon as it has departed from your lips, you shall observe and do just as you have promised to the Lord your God and just as you have spoken by your own free will and with your own mouth.
24 Upon entering your neighbor's vineyard, you may eat as many grapes as you please. But you may not carry any out with you.
25 If you enter into your friend's grain field, you may break off the ears, and rub them in your hand, but you may not reap them with a sickle."
