'Oath' in the Bible

Take heart and be strong; for you will give to this people for their heritage the land which I gave by an oath to their fathers.

So now, will you give me your oath by the Lord, that, because I have been kind to you, you will be kind to my father's house,

And the men said to her, We will only be responsible for this oath which you have made us take,

But if you say anything about our business here, then we will be free from the oath you have made us take.

For the children of Israel were wandering in the waste land for forty years, till all the nation, that is, all the fighting-men, who had come out of Egypt, were dead, because they did not give ear to the voice of the Lord: to whom the Lord said, with an oath, that he would not let them see the land which the Lord had given his word to their fathers to give us, a land flowing with milk and honey.

Then Joshua said to the two men who had been sent to make a search through the land, Go into the house of the loose woman, and get her out, and all who are with her, as you gave her your oath.

Then Joshua gave the people orders with an oath, saying, Let that man be cursed before the Lord who puts his hand to the building up of this town: with the loss of his first son will he put the first stone of it in place, and with the loss of his youngest son he will put up its doors.

So Joshua made peace with them, and made an agreement with them that they were not to be put to death: and the chiefs of the people took an oath to them.

And the children of Israel did not put them to death, because the chiefs of the people had taken an oath to them by the Lord, the God of Israel. And all the people made an outcry against the chiefs.

But all the chiefs said to the people, We have taken an oath to them by the Lord, the God of Israel, and so we may not put our hands on them.

This is what we will do to them: we will not put them to death, for fear that wrath may come on us because of our oath to them.

And on that day Moses took an oath, saying, Truly the land where your feet have been placed will become a heritage for you and your children for ever, because you have been true to the Lord your God with all your heart.

So the Lord gave to Israel all the land which he gave by oath to their fathers; so it became their heritage and their living-place.
