'For Us' in the Bible

But Jesus, answering, said to him, "Allow it now, for this is the fitting way for us to fulfill all righteousness." Then he allowed him.

Peter answered, and said to Jesus, "Lord, it is good for us to be here. If you want, let us make three tents here: one for you, one for Moses, and one for Elijah."

But the wise answered, saying, 'What if there is not enough for us and you? You go rather to those who sell, and buy for yourselves.'
