'Behaved' in the Bible

So David went out wherever Saul sent him, and he acted wisely and prospered; and Saul appointed him over the men of war. And it pleased all the people and also Saul’s servants.

Then the Philistine commanders (princes) came out to battle, and it happened as often as they did, that David acted more wisely and had more success than all Saul’s servants. So his name was highly esteemed.
