1 Samuel 17:14

And David was the youngest,.... For the sake of whom this account is given of Jesse and his family, and who after this makes a considerable figure in the camp and court of Saul:

and the three eldest followed Saul; as before related, and which is repeated, that it might be observed that they only of Jesse's sons followed Saul; not David particularly, but who was providentially sent to the army at the time the Philistine was defying it.
