'Commitment' in the Bible

“If a woman marries while her vows or the rash commitment she herself made are binding,

But if her husband prohibits her when he hears about it, he will cancel her vow that is binding or the rash commitment she herself made, and the Lord will forgive her.

But if he cancels them after he hears about them, he will be responsible for her commitment.”

the Jews bound themselves, their descendants, and all who joined with them to a commitment that they would not fail to celebrate these two days each and every year according to the written instructions and according to the time appointed.
