1 Maccabees 1:11–15

11 In those days lawless men came forth from Israel, and misled many, saying, “Let us go and make a covenant with the Gentiles round about us, for since we separated from them many evils have come upon us.” 12 This proposal pleased them, 13 and some of the people eagerly went to the king. He authorized them to observe the ordinances of the Gentiles. 14 So they built a gymnasium in Jerusalem, according to Gentile custom, 15 and removed the marks of circumcision, and abandoned the holy covenant. They joined with the Gentiles and sold themselves to do evil.
