'Fulfill' in the Bible

“This is the ritual of the Nazirite who vows his offering to the Lord for his consecration, in addition to whatever else he can afford; he must fulfill whatever vow he makes in keeping with the ritual for his consecration.”

He may assist his brothers to fulfill responsibilities at the tent of meeting, but he must not do the work. This is how you are to deal with the Levites regarding their duties.”

and you make a fire offering to the Lord from the herd or flock—either a burnt offering or a sacrifice, to fulfill a vow, or as a freewill offering, or at your appointed festivals—to produce a pleasing aroma for the Lord,

“If you prepare a young bull as a burnt offering or as a sacrifice, to fulfill a vow, or as a fellowship offering to the Lord,

God is not a man who lies,or a son of man who changes His mind.Does He speak and not act,or promise and not fulfill?

"When a man makes a vow to the LORD, or swears an oath an obligation that is binding to himself he is not to break his word. Instead, he is to fulfill whatever promise came out of his mouth.'"

and her father hears her vow and the obligations that she had pledged herself to fulfill, yet her father keeps silent about it, then all her vows and every obligation she pledged herself to are to stand.

But if her father disallows her on the same day that he hears what she has said, then all her vows and every obligation she had pledged herself to fulfill are not to stand. The LORD will forgive her, because her father has forbidden her."

"If she has a husband and she makes a vow that is binding on herself, or if she makes a hasty vow with her mouth that she pledges herself to fulfill,

But if, on the same day her husband hears and disallows her, then he has revoked her vows that she made for herself, along with any hasty vows that she spoke and to which she pledged herself to fulfill. The LORD will forgive her."

"Everything that a widow or a divorced woman pledges herself to fulfill are to be binding on her.

and her husband hears it but remains silent, not disallowing it, then all her vows are to stand, along with every obligation that she has pledged to fulfill.

But if her husband remains silent about her from day to day, then he has affirmed all her vows or obligations that she has obligated herself to fulfill. He has affirmed them because he remained silent from the day he heard her vows.
