Deuteronomy 23:23 Meaning and Commentary

Deuteronomy 23:23

That which is gone out of thy lips thou shalt keep and
perform
Which were in their power to perform and lawful to do; and this is observed to make them watchful and cautious, and not be rash in making vows, since, when once they were made, an exact and rigid performance of them was expected; see ( Ecclesiastes 5:4 Ecclesiastes 5:5 ) ;

[even] a freewill offering, according as thou hast vowed unto the Lord
thy God, which thou hast promised with thy mouth;
be it what it will, as to the matter of it, it was to be paid, and in the manner as it was vowed and promised. Aben Ezra observes, that every vow is a freewill offering, but not every freewill offering a vow; the Targum of Jonathan enumerates the several things to be performed, sin offerings, trespass offerings, burnt offerings, and oblations of holy things, and drink offerings, and gifts of the house of the sanctuary, and alms to the poor.

Deuteronomy 23:23 In-Context

21 "If you make a vow to the LORD your God, you shall not delay fulfilling it, for the LORD your God will surely require it of you, and you will be guilty of sin

22 But if you refrain from vowing, you will not be guilty of sin.

23 You shall be careful to do what has passed your lips, for you have voluntarily vowed to the LORD your God what you have promised with your mouth.

24 "If you go into your neighbor's vineyard, you may eat your fill of grapes, as many as you wish, but you shall not put any in your bag.

25 If you go into your neighbor's standing grain, you may pluck the ears with your hand, but you shall not put a sickle to your neighbor's standing grain.
