III Maccabees 7:5

5 They brought them fettered in grievous chains as slaves, nay, as traitors. Without enquiry or examination they endeavoured to annihilate them. They buckled themselves with a savage cruelty, worse than Scythian custom.

III Maccabees 7:5 In-Context

3 Certain of our friends did of malice vehemently urge us to punish the Jews of our realm in a body, with the infliction of a monstrous punishment.
4 They pretended that our affairs would never be in a good state till this took place. Such, they said, was the hatred borne by the Jews to all other people.
5 They brought them fettered in grievous chains as slaves, nay, as traitors. Without enquiry or examination they endeavoured to annihilate them. They buckled themselves with a savage cruelty, worse than Scythian custom.
6 For this cause we severely threatened them; yet, with the clemency which we are wont to extend to all men, we at length permitted them to live. Finding that the God of heaven cast a shield of protection over the Jews so as to preserve them, and that he fought for them as a father always fights for his sons;
7 and taking into consideration their constancy and fidelity towards us and towards our ancestors, we have, as we ought, acquitted them of every sort of charge.
