Leviticus 27:9-10

Redemption of Vowed Animals

27:9 “‘If what is vowed is a kind of animal from which an offering may be presented to the Lord, anything which he gives to the Lord from this kind of animal will be holy. 27:10 He must not replace or exchange it, good for bad or bad for good, and if he does indeed exchange one animal for another animal, then both the original animal and its substitute will be holy.

Leviticus 27:31

Numbers 30:2-16

30:2 If a man makes a vow to the Lord or takes an oath of binding obligation on himself, he must not break his word, but must do whatever he has promised.

Vows Made by Single Women

30:3 “If a young woman who is still living in her father’s house makes a vow to the Lord or places herself under an obligation, 30:4 and her father hears of her vow or the obligation to which she has pledged herself, and her father remains silent about her, then all her vows will stand, and every obligation to which she has pledged herself will stand. 30:5 But if her father overrules her when he hears about it, then none of her vows or her obligations which she has pledged for herself will stand. And the Lord will release her from it, because her father overruled her.

Vows Made by Married Women

30:6 “And if she marries a husband while under a vow, or she uttered anything impulsively by which she has pledged herself, 30:7 and her husband hears about it, but remains silent about her when he hears about it, then her vows will stand and her obligations which she has pledged for herself will stand. 30:8 But if when her husband hears it he overrules her, then he will nullify the vow she has taken, and whatever she uttered impulsively which she has pledged for herself. And the Lord will release her from it.

Vows Made by Widows

30:9 “But every vow of a widow or of a divorced woman which she has pledged for herself will remain intact. 30:10 If she made the vow in her husband’s house or put herself under obligation with an oath, 30:11 and her husband heard about it, but remained silent about her, and did not overrule her, then all her vows will stand, and every obligation which she pledged for herself will stand. 30:12 But if her husband clearly nullifies them when he hears them, then whatever she says by way of vows or obligations will not stand. Her husband has made them void, and the Lord will release her from them.

30:13 “Any vow or sworn obligation that would bring affliction to her, her husband can confirm or nullify. 30:14 But if her husband remains completely silent about her from day to day, he thus confirms all her vows or all her obligations which she is under; he confirms them because he remained silent about when he heard them. 30:15 But if he should nullify them after he has heard them, then he will bear her iniquity.”

30:16 These are the statutes that the Lord commanded Moses, relating to a man and his wife, and a father and his young daughter who is still living in her father’s house.

Ecclesiastes 5:4-6

5:4 When you make a vow to God, do not delay in paying it.

For God takes no pleasure in fools:

Pay what you vow!

5:5 It is better for you not to vow

than to vow and not pay it.

5:6 Do not let your mouth cause you to sin,

and do not tell the priest, “It was a mistake!”

Why make God angry at you

so that he would destroy the work of your hands?”

Matthew 5:33

Oaths

5:33 “Again, you have heard that it was said to an older generation, ‘Do not break an oath, but fulfill your vows to the Lord.’
