'For Us' in the Bible

And Jesus answering said unto him, Permit it to be so now: for thus it is fitting for us to fulfill all righteousness. Then he permitted him.

Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if you will, let us make here three tabernacles; one for you, and one for Moses, and one for Elijah.

But the wise answered, saying, Not so; lest there be not enough for us and you: but go you rather to them that sell, and buy for yourselves.
