Matthew Henry Presbyterian @wholebiblehenry

Here we have, I. The preparation which the Ammonites made for war, Sa2 10:6. They saw they had made themselves very odious to David and obnoxious to his just displeasure. This they might easily have foreseen when they abused his ambassadors, which was no other than a challenge to war, and a bold defiance of him.

And when David heard of it,.... Of the preparation made by the Ammonites to fight with him: he sent Joab and all the host of the mighty men: he sent out Joab his general, and an army under his command, consisting of men of strength, valour, and courage; or all the host and the mighty men, as Kimchi and Ben Melech, the famous mighty men...

All the host of the mighty - All his worthies, and the flower of his army.
