'Sworn' in the Bible

Wherever they went, the hand of the Lord was against them for evil (misfortune), as the Lord had spoken, and as the Lord had sworn to them, so that they were severely distressed.

Now the men of Israel had sworn [an oath] at Mizpah, “None of us shall give his daughter in marriage to [a man of] Benjamin.”

What shall we do for wives for those who are left, since we have sworn [an oath] by the Lord that we will not give them any of our daughters as wives?”

But we cannot give them wives from our daughters.” For the sons of Israel had sworn [an oath], “Cursed is he who gives a wife to [a man from the tribe of] Benjamin.”
