'Sworn' in the Bible

Wherever they went out, the hand of Yahweh was against them for evil, as Yahweh had spoken, and as Yahweh had sworn to them: and they were very distressed.

Now the men of Israel had sworn in Mizpah, saying, "There shall not any of us give his daughter to Benjamin as wife."

How shall we provide wives for those who remain, since we have sworn by Yahweh that we will not give them of our daughters to wives?"

However we may not give them wives of our daughters, for the children of Israel had sworn, saying, 'Cursed is he who gives a wife to Benjamin.'"
