2 Samuel 18:6-8

Amplified Bible

⁶ So the men went out into the field against Israel, and the battle was fought in the forest of Ephraim. ⁷ The men of Israel [who supported Absalom] were defeated there by the ^[a]men of David, and a great slaughter took place there that day, 20,000 men. ⁸ For the battle there was spread out over the surface of the entire countryside, and the [hazards of the] forest devoured more men that day than did the sword.
