1 Maccabees 2:46

39 When Mattathias and his friends learned of it, they mourned for them deeply. 40 And all said to their neighbors: "If we all do as our kindred have done and refuse to fight with the Gentiles for our lives and for our ordinances, they will quickly destroy us from the earth." 41 So they made this decision that day: "Let us fight against anyone who comes to attack us on the sabbath day; let us not all die as our kindred died in their hiding places." 42 Then there united with them a company of Hasideans, mighty warriors of Israel, all who offered themselves willingly for the law. 43 And all who became fugitives to escape their troubles joined them and reinforced them. 44 They organized an army, and struck down sinners in their anger and renegades in their wrath; the survivors fled to the Gentiles for safety. 45 And Mattathias and his friends went around and tore down the altars; 46 they forcibly circumcised all the uncircumcised boys that they found within the borders of Israel. 47 They hunted down the arrogant, and the work prospered in their hands.

Galatians 5:12

1 For freedom Christ has set us free. Stand firm, then, and do not be subject again to the yoke of slavery. 2 Listen! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no benefit to you at all! 3 And I testify again to every man who lets himself be circumcised that he is obligated to obey the whole law. 4 You who are trying to be declared righteous by the law have been alienated from Christ; you have fallen away from grace! 5 For through the Spirit, by faith, we wait expectantly for the hope of righteousness. 6 For in Christ Jesus neither circumcision nor uncircumcision carries any weight—the only thing that matters is faith working through love. 7 You were running well; who prevented you from obeying the truth? 8 This persuasion does not come from the one who calls you! 9 A little yeast makes the whole batch of dough rise! 10 I am confident in the Lord that you will accept no other view. But the one who is confusing you will pay the penalty, whoever he may be. 11 Now, brothers and sisters, if I am still preaching circumcision, why am I still being persecuted? In that case the offense of the cross has been removed. 12 I wish those agitators would go so far as to castrate themselves!
