1 Maccabees 9:5-7

New Catholic Bible

⁵ Judas meanwhile had encamped at Elasa with three thousand picked men. ⁶ When his men saw the immense number of the enemy forces, they were greatly terrified, and many slipped away from the camp, until only eight hundred men remained.

⁷ When Judas realized that the battle was imminent and that his army was melting away, he became despondent, for he had no time to redeploy them.
