1macc 1:62
King James Version
“Howbeit many in Israel were fully resolved and confirmed in themselves not to eat any unclean thing.”
Context
59Now the five and twentieth day of the month they did sacrifice upon the idol altar, which was upon the altar of God.
60At which time according to the commandment they put to death certain women, that had caused their children to be circumcised.
61And they hanged the infants about their necks, and rifled their houses, and slew them that had circumcised them.
62Howbeit many in Israel were fully resolved and confirmed in themselves not to eat any unclean thing.
63Wherefore the rather to die, that they might not be defiled with meats, and that they might not profane the holy covenant: so then they died.
64And there was very great wrath upon Israel.
