2 Maccabees 10:17-19

New Revised Standard Version Catholic Edition

¹⁷ Attacking them vigorously, they gained possession of the places, and beat off all who fought upon the wall, and slaughtered those whom they encountered, killing no fewer than twenty thousand.

¹⁸ When at least nine thousand took refuge in two very strong towers well equipped to withstand a siege, ¹⁹ Maccabeus left Simon and Joseph, and also Zacchaeus and his troops, a force sufficient to besiege them; and he himself set off for places where he was more urgently needed.
