'Vowed' in the Bible

Now the length of time it took for us to go from Kadesh Barnea to the crossing of Wadi Zered was thirty-eight years, time for all the military men of that generation to die, just as the Lord had vowed to them.

But the Lord became angry with me because of you and vowed that I would never cross the Jordan nor enter the good land that he is about to give you.

Rather it is because of his love for you and his faithfulness to the promise he solemnly vowed to your ancestors that the Lord brought you out with great power, redeeming you from the place of slavery, from the power of Pharaoh king of Egypt.

You will not be allowed to eat in your villages your tithe of grain, new wine, olive oil, the firstborn of your herd and flock, any votive offerings you have vowed, or your freewill and personal offerings.

Whatever you vow, you must be careful to do what you have promised, such as what you have vowed to the Lord your God as a freewill offering.
