'Feed' in the Bible

When therefore they had dined, Jesus says to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He says to him, Yea, Lord; thou knowest that I am attached to thee. He says to him, Feed my lambs.

He says to him the third time, Simon, son of Jonas, art thou attached to me? Peter was grieved because he said to him the third time, Art thou attached to me? and said to him, Lord, thou knowest all things; thou knowest that I am attached to thee. Jesus says to him, Feed my sheep.
