'For Us' in the Bible

But the people answered, You shall not go forth: for if we flee away, they will not care for us; neither if half of us die, will they care for us: but now you are worth ten thousand of us: therefore now it is better that you support us from out of the city.

And the Gibeonites said unto him, We will have no silver nor gold of Saul, nor of his house; neither for us shall you kill any man in Israel. And he said, What you shall say, that will I do for you.
