'Swore' in the Bible

Be strong and confident and courageous, for you will give this people as an inheritance the land which I swore to their fathers (ancestors) to give them.

For the Israelites walked forty years in the wilderness, until all the nation, that is, the men of war who came out of Egypt, died because they did not listen to the voice of the Lord; to them the Lord had sworn [an oath] that He would not let them see the land which He had promised to their fathers to give us, a land [of abundance] flowing with milk and honey.

But Joshua said to the two men who had spied out the land, “Go into the prostitute’s house and bring the woman and all that she has out of there, as you have sworn to her.”

Joshua made peace with them and made a covenant (treaty) with them, to let them live; and the leaders of the congregation [of Israel] swore an oath to them.

This [is what] we will do to them: we will let them live, so that the wrath [of God] does not come upon us for [violating] the oath which we have sworn to them.”

So Moses swore [an oath to me] on that day, saying, ‘Be assured that the land on which your foot has walked will be an inheritance to you and to your children always, because you have followed the Lord my God completely.’
