'Us' in the Bible

Blessed be the God and Father of our Lord Jesus Christ, who according to his great mercy begat us again unto a living hope by the resurrection of Jesus Christ from the dead,

Because Christ also suffered for sins once, the righteous for the unrighteous, that he might bring us to God; being put to death in the flesh, but made alive in the spirit;

For the time is come for judgment to begin at the house of God: and if it begin first at us, what'shall be the end of them that obey not the gospel of God?
