If you said you would do it, you made a promise – you made a vow. Are you faithful to keep that vow? As humans it is so easy to break it, don’t you agree? Jesus said “But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.” (Matthew 5:37) From His words, I think we can see that when we break a vow it is never good. Let’s see what else the Bible has to say about keeping vows .
You Are Held Accountable for Your Vow with the LORD
Exodus 24:7 And he [Moses] took the book of the covenant, and read in the audience of the people: and they said, All that the LORD hath said will we do, and be obedient.

Deuteronomy 23:21–23 When thou shalt vow a vow unto the LORD thy God, thou shalt not slack to pay it: for the LORD thy God will surely require it of thee; and it would be sin in thee. But if thou shalt forbear to vow, it shall be no sin in thee. That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.
Ecclesiastes 5:4–5 When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed. Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.

Amen.
The New Covenant (Testament)
Jeremiah 31:31–33 Behold, the days come, saith the LORD, That I will make a new covenant With the house of Israel, and with the house of Judah: Not according to the covenant that I made with their fathers In the day that I took them by the hand To bring them out of the land of Egypt; Which my covenant they brake, Although I was an husband unto them, saith the LORD: But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, And write it in their hearts; And will be their God, And they shall be my people.

Great Examples of Covenants (Vows) in the Bible
Between Jacob (Israel) and God
Genesis 28:20–22 And Jacob vowed a vow, saying, If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on, So that I come again to my father’s house in peace; then shall the LORD be my God: And this stone, which I have set for a pillar, shall be God’s house: and of all that thou shalt give me I will surely give the tenth unto thee.
Numbers 21:2 And Israel vowed a vow unto the LORD, and said, If thou wilt indeed deliver this people into my hand, then I will utterly destroy their cities.
Between Jephthah and God
Judges 11:30–31 And Jephthah vowed a vow unto the LORD, and said, If thou shalt without fail deliver the children of Ammon into mine hands, Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the LORD’s, and I will offer it up for a burnt offering.
Between Hannah and God
1 Samuel 1:11 And she vowed a vow, and said, O LORD of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the LORD all the days of his life, and there shall no rasor come upon his head.
Between the Men on Jonah’s Ship and the LORD
Jonah 1:14–16 Wherefore they cried unto the LORD, and said, We beseech thee, O LORD, we beseech thee, let us not perish for this man’s life, and lay not upon us innocent blood: for thou, O LORD, hast done as it pleased thee. So they took up Jonah, and cast him forth into the sea: and the sea ceased from her raging. Then the men feared the LORD exceedingly, and offered a sacrifice unto the LORD, and made vows.
No doubt, for as long as we live on earth, we will make vows. Let it be our heart’s desire to keep the vows that we make. When we say “Yes” let us mean “Yes” and when we say “No” let us mean “No”. Though it be challenging as humans, we can succeed through the power of the Holy Spirit to do “whatsoever things are true, whatsoever things are honest” (Phil 4:8).
