'For Us' in the Bible

And they said, Come, let us build a city for us, and a tower, and its top in the heavens. And let us make a name for us, lest we be scattered abroad upon the face of the whole earth.

and said, Whose daughter are thou? Tell me, I pray thee. Is there room in thy father's house for us to lodge in?

And he moved from there, and dug another well, and they did not strive for that. And he called the name of it Rehoboth. And he said, For now LORD has made room for us, and we shall be fruitful in the land.

And Rachel and Leah answered and said to him, Is there yet any portion or inheritance for us in our father's house?

And he said, Behold, I have heard that there is grain in Egypt. Get you down there, and buy for us from there, that we may live, and not die.
