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 “When you make a vow to the LORD your God, be prompt in fulfilling whatever you promised him. For the LORD your God demands that you promptly fulfill all your vows, or you will be guilty of sin.

22 However, it is not a sin to refrain from making a vow.

23 But once you have voluntarily made a vow, be careful to fulfill your promise to the LORD your God.

24 “When you enter your neighbor’s vineyard, you may eat your fill of grapes, but you must not carry any away in a basket.

25 And when you enter your neighbor’s field of grain, you may pluck the heads of grain with your hand, but you must not harvest it with a sickle.
