'Feed My Sheep' in the Bible

As I live, says the Lord Yahweh, surely because my sheep became a prey, and my sheep became food to all the animals of the field, because there was no shepherd, neither did my shepherds search for my sheep, but the shepherds fed themselves, and didn't feed my sheep;

I will feed My flock and I will let them lie down [to rest],” says the Lord God.

He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.

He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.

Jesus told him, "Feed my sheep. "Truly, I tell you emphatically, when you were young, you would fasten your belt and go wherever you liked. But when you get old, you will stretch out your hands, and someone else will fasten your belt and take you where you don't want to go."
