However those who make vows should fulfill them at any cost. If you make a vow to the Lord your God, do not be slow to pay it, for the Lord your God will certainly demand it of you and you will be guilty of sin. But if you refrain from making a vow, you will not be guilty of sin. Jacob fulfilled that vow. You too should fulfill your vow.
Some people make foolish vows and struggle later unable to fulfill the vow.
It is better to obtain counsel from saints above us to avoid such mistakes. Making vow is a matter of honor to the Lord. Don't delay but fulfill it at once. After making vow, don't say that you have done it by mistake. Fulfill without delay any vow, which you have made for your good or profit.
