David was the youngest son. The three oldest sons were in Saul’s army.
The Lord said to her, “Two nations are in your body. The rulers of two families will be born from you. And they will be divided. One son will be stronger than the other. The older son will serve the younger.”
Then Samuel asked Jesse, “Are these all the sons you have?”
But David left Saul from time to time to take care of his father’s sheep at Bethlehem.
