1 Samuel 16, 1.4.6-13
Yahweh said to Samuel, 'How much longer do you mean to go on mourning over Saul, now that I myself have rejected him as ruler of Israel? Fill your horn with oil and go. I am sending you to Jesse of Bethlehem, for I have found myself a king from among his sons.'
Samuel did what Yahweh ordered and went to Bethlehem. The elders of the town came trembling to meet him and asked, 'Seer, is your coming favourable for us,'
When they arrived, he looked at Eliab and thought, 'This must be Yahweh's anointed now before him,'
but Yahweh said to Samuel, 'Take no notice of his appearance or his height, for I have rejected him; God does not see as human beings see; they look at appearances but Yahweh looks at the heart.'
Jesse then called Abinadab and presented him to Samuel, who said, 'Yahweh has not chosen this one either.'
Jesse then presented Shammah, but Samuel said, 'Yahweh has not chosen this one either.'
Jesse thus presented seven of his sons to Samuel, but Samuel said to Jesse, 'Yahweh has not chosen these.'
He then asked Jesse, 'Are these all the sons you have?' Jesse replied, 'There is still one left, the youngest; he is looking after the sheep.' Samuel then said to Jesse, 'Send for him, for we shall not sit down to eat until he arrives.'
Jesse had him sent for; he had ruddy cheeks, with fine eyes and an attractive appearance. Yahweh said, 'Get up and anoint him: he is the one!'
At this, Samuel took the horn of oil and anointed him, surrounded by his brothers; and the spirit of Yahweh seized on David from that day onwards. Samuel, for his part, set off and went to Ramah.
