2 Samuel 17:9,10

Behold, he is now hid in some pit Having been often accustomed to that course, and well acquainted with all hiding-places from Saul's time. In one of them, unknown to us, he will lurk with some of his chosen men, and lie in ambush for us; and when they see a fit opportunity, they will suddenly come forth and surprise some of our men, when they least expect it, and probably at first put them to flight. When some of them be overthrown Namely, of Absalom's men sent against David. At the first Implying, that their good success at first would mightily animate David's men to proceed vigorously in the fight, and intimidate Absalom's army, and consequently would be both a presage and an occasion of their total defeat. Whosoever heareth it will say, &c. They who first hear these ill tidings will propagate them, and strike terror with them into the rest of the army, whose fear will make them think the slaughter greater than it is. He also that is valiant shall utterly melt For men, even the most valiant, are apt to form conjectures of the final issue by the beginning; and it is a great encouragement to men to fight, when they prosper at the first onset, and a great discouragement when they are worsted. All Israel knoweth that thy father is a valiant man, &c. The known fame of the prodigious valour of thy father and his followers will easily gain credit to the report of their being victorious, and strike the stoutest of our men with dread, even Ahithophel himself, if he should go with them.
