The Lord said to Samuel, 'How long will you go on mourning over Saul when I have rejected him as king of Israel? Fill your horn with oil and go, I am sending you to Jesse of Bethlehem, for I have chosen myself a king from among his sons.' Samuel replied, 'How can I go? When Saul hears of this he will kill me.' Then the Lord said, 'Take an heifer with you and say, "I have come to sacrifice to the Lord'. Invite Jesse to the sacrifice, and then I myself will tell you what you must do; you must anoint to me the one I point out to you.' (1 Samuel 16:1-3)
He then said to Jesse, 'Are these all the sons you have? He answered , 'There is still one left, the youngest; he is out looking after the sheep'. Then Samuel said to Jesse, 'Send for him; we will not sit down to eat until he comes'. Jesse had him sent for, a boy of fresh complexion, with fine eyes and pleasant bearing. The Lord said, 'Come, anoint him, for this is the one'. At this, Samuel took the horn of oil and anointed him where he stood with his brothers; and the spirit of the Lord seized on David and stayed with him from that day on. (1 Samuel 16:11-13)
The King of love my shepherd is,
Whose goodness faileth never;
I nothing lack if I am his
And he is mine for ever.
Where streams of living water flow
My ransomed soul he leadeth,
And where the verdant pastures grow
With food celestial feedeth.
Thou spread'st a table in my sight;
Thy unction grace bestoweth:
And O what transport of delight
From thy pure chalice floweth!
And so through all the length of days
Thy goodness faileth never;
Good Shepherd, may I sing thy praise
Within thy house for ever.
