2 Samuel 18:8 - Wesley's Explanatory Notes

The wood — More people died in the wood, either through hunger, and thirst, and weariness: or, by the wild beasts, whereof great numbers were there, which, though they were driven away from the place of the main battle, yet might easily meet with them when they fled several ways: or, by falling into ditches and pits, which were in that place, 2 Samuel 18:17, and probably were covered with grass or wood, so that they could not see them till they fell into them: and especially by David's men, who pursued them, and killed them in the wood: and the wood is rightly said to have devoured them, because it gave the occasion to their destruction, inasmuch as the trees, and ditches, and pits, entangled them, and stopped their flight, and made them an easy prey to David's men, who followed them, and slew them in the pursuit. The sword — In the main battle: the sword being put for the battle, by a common figure.
