'For Us' in the Bible

And has raised up a horn of salvation for us in the house of his servant David;

And it came to pass, as they departed from him, Peter said unto Jesus, Teacher, it is good for us to be here: and let us make three tabernacles; one for you, and one for Moses, and one for Elijah: not knowing what he said.

And Jesus said unto him, Forbid him not: for he that is not against us is for us.

Is it lawful for us to give tribute unto Caesar, or not?
