David went out wherever Saul sent him, [and] behaved himself wisely: and Saul set him over the men of war, and it was good in the sight of all the people, and also in the sight of Saul's servants.
Saul responded to Jonathan’s affection for David, and presumably David’s bravery, by keeping David with him even more than the king had done previously (1 Samuel 18:2; cf. 1 Samuel 14:52). Evidently Jonathan realized David’s gifts and God’s will for David’s life (cf. 1 Samuel 23:17), and he humbly deferred to him (1 Samuel 18:3-4).
