'Us' in the Bible

For the truth's sake, which dwelleth in us, and shall be with us for ever.

Grace, mercy, and peace will be with us from God the Father and from Jesus Christ, the Son of the Father, in truth and love.

I was overjoyed to find some of your children living truthfully, just as the Father has commanded us.

And now, dear lady, I pray you--writing to you, as I do, not a new command, but the one which we have had from the very beginning--let us love one another.
