'Pledged' in the Bible

Indeed, your servant pledged security for the boy with my father, saying, 'If I do not bring him back to you, then I will bear the blame before my father all my life.'

and her father hears of her vow or the obligation to which she has pledged herself, and her father remains silent about her, then all her vows will stand, and every obligation to which she has pledged herself will stand.

But if her father overrules her when he hears about it, then none of her vows or her obligations which she has pledged for herself will stand. And the Lord will release her from it, because her father overruled her.

"And if she marries a husband while under a vow, or she uttered anything impulsively by which she has pledged herself,

and her husband hears about it, but remains silent about her when he hears about it, then her vows will stand and her obligations which she has pledged for herself will stand.

But if when her husband hears it he overrules her, then he will nullify the vow she has taken, and whatever she uttered impulsively which she has pledged for herself. And the Lord will release her from it.

"But every vow of a widow or of a divorced woman which she has pledged for herself will remain intact.

and her husband heard about it, but remained silent about her, and did not overrule her, then all her vows will stand, and every obligation which she pledged for herself will stand.

If the Lord your God enlarges your borders as he promised your ancestors and gives you all the land he pledged to them,

All the officers and warriors, as well as all of King David's sons, pledged their allegiance to King Solomon.
