'Sworn' in the Bible

But the sons of Israel did not strike them because the leaders of the congregation had sworn to them by the Lord the God of Israel [to spare them]. And all the congregation murmured [expressing great dissatisfaction] against the leaders.

But all the leaders said to the whole congregation, “We have sworn to them by the Lord, the God of Israel, so now we cannot touch them.

So the Lord gave Israel all the land which He had sworn to give to their fathers (ancestors), and they took possession of it and lived in it.

The Lord gave them rest [from conflict] on every side, in accordance with everything that He had sworn to their fathers, and not one of all their enemies stood before them [in battle]; the Lord handed over all their enemies to them.
