I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called.
I am the good shepherd; the good shepherd lays down His life for the sheep. He who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees, and the wolf snatches them and scatters them. He flees because he is a hired hand and is not concerned about the sheep. I am the good shepherd, and I know My own and My own know Me, even as the Father knows Me and I know the Father; and I lay down My life for the sheep. (John 10:11-15 NASB)
Then they asked for a king, and God gave them Saul the son of Kish, a man of the tribe of Benjamin, for forty years. After He had removed him, He raised up David to be their king, concerning whom He also testified and said, "I have found David the son of Jesse, a man after My heart, who will do all My will." (Acts 13:21-22 NASB)
