Vows are usually associated with weddings, as in someone took marriage vows. Maybe I’ve read it for monastic orders as well. Really we don’t hear the word any more–at least I don’t. Perhaps that is part of the reason people so easily break their word. Marriage is a big vow–you vow your life. There are also every day little vows. “I’ll get that done.” “You’ll have it next week.”
In the Bible “vow” is usually used with regards to paying what we’ve said we would pay. “Keep you word” would be the modern translation, especially with regards to money.
If a man makes a vow to the Lord, or takes an oath to bind himself with a binding obligation, he shall not violate his word; he shall do according to all that proceeds out of his mouth (Numbers 30:2).
You shall be careful to perform what goes out from your lips, just as you have voluntarily vowed to the Lord your God, what you have promised (Deuteronomy 23:23).
When you make a vow to God, do not be late in paying it, for He takes no delight in fools. Pay what you owe! (Ecclesiastes 5:4).
It is better that you should not vow than that you should vow and not pay (Ecclesiastes 5:5).
Any “earnest promise or pledge that binds one perform in a certain manner” is a vow (The Word on Finances).If you’re word means something to you, unpaid vows may hang over your heard until fulfilled. That’s probably conscience urging you to do right just as God’s word does. My own to-do list is packed with small vows that I’m not always the best at performing. It seems so simple, but it is an area where I need to improve.
