'For Us' in the Bible

Then said Peter to Jesus, Master, it is good for us to be here: let us make three tabernacles; one for Thee, and one for Moses, and one for Elias:

for he that is not against us, is for us.

Then come to Him James and John, the sons of Zebedee, saying, Master, we desire that thou wouldest do for us what we shall request:

And he will shew you a large upper room ready prepared, there make preparation for us.

And they said to one another, Who will roll away the stone for us from the door of the sepulchre?
