נָדַר (nādar) is a Hebrew verb meaning to make a vow, especially an undertaking to the Lord. The act is a commitment a person makes, not a promise God owes in return. Deuteronomy 23:21-23 distinguishes freely undertaking a vow from refraining: a vow must be fulfilled, while abstaining from one is not itself sinful. That distinction protects readers from treating heightened verbal commitment as a necessary proof of devotion.
Hannah vows amid anguished prayer in 1 Samuel 1:11, while Jonah speaks of fulfilling his vows in a prayer that confesses salvation belongs to the Lord. These contexts allow grief, petition, dedication, and gratitude to be heard without turning their particular experiences into a formula. The verb does not promise that an equivalent vow will produce a child or rescue. Its teaching value lies in the relationship between freely offered commitment, honest follow-through, and dependence upon God's mercy.
Selected vow-making texts distinguish voluntary undertaking from required faithfulness once words have been spoken. Hannah's petition and Jonah's thanksgiving provide distinct narrative settings, while Deuteronomy supplies an explicit limit against making vows compulsory.
If you make a vow to the Lord your God, do not be slow to keep it, because He will surely require it of you, and you will be guilty of sin.
The instruction concerns a vow actually made to the Lord and forbids delay in keeping it. The adjacent permission not to vow prevents this obligation from becoming a demand that everyone make additional commitments.
But if you refrain from making a vow, you will not be guilty of sin.
Refraining from making a vow is explicitly distinguished from sinful failure to fulfill one. This direct occurrence gives teachers a textual boundary against compulsory pledges or spiritual competition.
And she made a vow, saying, “O Lord of Hosts, if only You will look upon the affliction of Your maidservant and remember me, not forgetting Your maidservant but giving her a son, then I will dedicate him to the Lord all the days of his life, and no razor shall ever touch his head.”
Hannah's undertaking arises within her particular distressed prayer and concerns the dedication of the son she requests. Her story does not authorize blaming another grieving person for lacking an equivalent vow.
But I, with the voice of thanksgiving, will sacrifice to You. I will fulfill what I have vowed. Salvation is from the Lord!”
Jonah's resolve to fulfill his vow stands beside thanksgiving and the confession that salvation belongs to the Lord. The prayer's climax attributes deliverance to God rather than to the power of Jonah's undertaking.

Deuteronomy's instructions give weight to spoken commitment without rewarding the multiplication of commitments. The person who vows must not postpone fulfillment, because freely addressed words to the Lord are serious. Yet the person who refrains is not thereby guilty. The law does not turn every good intention into a mandatory ceremonial undertaking. Its distinction allows a teacher to commend honest fulfillment without coercing a congregation into promises its members did not freely choose.
Hannah's prayer should be heard with its tears and particular dedication; it must not become an explanation for someone else's unanswered petition. Jonah's willingness to fulfill what he vowed accompanies his confession that salvation comes from the Lord. Together these scenes direct attention toward dependence and grateful responsibility. They do not offer a price list for receiving divine help. Christian application should keep the reliability of ordinary speech in view while refusing to make an additional vow the condition of God's grace.
Deut.23.21
H5087 names the action of making a vow, whereas the related noun H5088 names a vow. Deuteronomy 23:22 uses the action in an instruction about refraining, so the verb itself does not encode a requirement to make the undertaking.
Israel's law treats a freely made vow as serious while permitting restraint from vow-making. Jesus' instruction in Matthew 5:33-37 calls disciples to dependable speech rather than elaborate assurances. The comparison helps teachers examine sincerity and responsibility, but a Hebrew vow and the Greek oath vocabulary remain distinct lexical objects. Neither passage offers a transaction that purchases divine favor.
