'For Us' in the Bible

So Jesus replied to him, "Let it happen now, for it is right for us to fulfill all righteousness." Then John yielded to him.

So Peter said to Jesus, "Lord, it is good for us to be here. If you want, I will make three shelters -- one for you, one for Moses, and one for Elijah."

Then Peter said to him, "Look, we have left everything to follow you! What then will there be for us?"

No,' they replied. 'There won't be enough for you and for us. Go instead to those who sell oil and buy some for yourselves.'

saying, "Prophesy for us, you Christ! Who hit you?"
