II Maccabees 10:18

18 And because certain, who were no less than nine thousand, were fled together into two very strong castles, having all manner of things convenient to sustain the siege,

II Maccabees 10:18 In-Context

16 Then they that were with Maccabeus made supplication, and besought God that he would be their helper; and so they ran with violence upon the strong holds of the Idumeans,
17 And assaulting them strongly, they won the holds, and kept off all that fought upon the wall, and slew all that fell into their hands, and killed no fewer than twenty thousand.
18 And because certain, who were no less than nine thousand, were fled together into two very strong castles, having all manner of things convenient to sustain the siege,
19 Maccabeus left Simon and Joseph, and Zaccheus also, and them that were with him, who were enough to besiege them, and departed himself unto those places which more needed his help.
20 Now they that were with Simon, being led with covetousness, were persuaded for money through certain of those that were in the castle, and took seventy thousand drachms, and let some of them escape.
