'He is the Lord' in the Bible

Then that disciple whom Jesus loved said to Peter, He is the Lord. Then Simon Peter hearing that He is the Lord, girded on his fishing-cloak (for he was unclothed), and cast Himself into the sea:

Jesus says to them, Come, take breakfast. But no one of the disciples dared to ask Him, Who art thou? knowing that He is the Lord.

and in him you have your fulness, and he is the Lord of all the principalities and powers.

These will make war against the Lamb, and the Lamb will overcome them, because he is the Lord of lords and King of kings; and those who are with him are named, marked out, and true.
