1 Maccabees 2:39–41

39 When Mattathias and his friends learned of it, they mourned for them deeply. 40 And each said to his neighbor: “If we all do as our brethren 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 every man who comes to attack us on the sabbath day; let us not all die as our brethren died in their hiding places.”
