'Sworn' in the Bible

But the {Israelites} did not attack them, because the leaders of the congregation had sworn to them by Yahweh the God of Israel. And all the congregation murmured {against their leaders}.

But all the leaders of the congregation said, "We have sworn to them by Yahweh the God of Israel, and so we cannot touch them.

Yahweh gave them rest on every side, according to all that he had sworn to their ancestors, and nobody from all their enemies withstood them, for Yahweh had given all their enemies into their hand.
