1 Maccabees 7:9-19

9 And him he sent with that wicked Alcimus, whom he made high priest, and commanded that he should take vengeance of the children of Israel.
10 So they departed, and came with a great power into the land of Judea, where they sent messengers to Judas and his brethren with peaceable words deceitfully.
11 But they gave no heed to their words; for they saw that they were come with a great power.
12 Then did there assemble unto Alcimus and Bacchides a company of scribes, to require justice.
13 Now the Assideans were the first among the children of Israel that sought peace of them:
14 For said they, One that is a priest of the seed of Aaron is come with this army, and he will do us no wrong.
15 So he spake unto them, peaceably, and sware unto them, saying, we will procure the harm neither of you nor your friends.
16 Whereupon they believed him: howbeit he took of them threescore men, and slew them in one day, according to the words which he wrote,
17 The flesh of thy saints have they cast out, and their blood have they shed round about Jerusalem, and there was none to bury them.
18 Wherefore the fear and dread of them fell upon all the people, who said, There is neither truth nor righteousness in them; for they have broken the covenant and oath that they made.
19 After this, removed Bacchides from Jerusalem, and pitched his tents in Bezeth, where he sent and took many of the men that had forsaken him, and certain of the people also, and when he had slain them, he cast them into the great pit.
