David captured 1,000 of his chariots, 1,700 horsemen, and 20,000 foot soldiers. David hamstrung all the chariot horses except for enough to supply 100 chariots.

David confiscated 1,000 chariots, 7,000 horsemen, and 20,000 foot soldiers from him, and hamstrung all of the chariot horses except for a reserve force of 100 chariots.
