LXX 2 Macc 6:11

ἕτεροι δὲ πλησίον συνδραμόντες εἰς τὰ σπήλαια λεληθότως ἅγειν τὴν ἑβδομάδα, μηνυθέντες τῷ Φιλίππῳ συνεφλογίσθησαν, διὰ τὸ εὐλαβῶς ἔχειν βοηθῆσαι αὐτοῖς κατὰ δόξαν τῆς σεμνοτάτης ἡμέρας.

And others that had met together in caves that were near, and were keeping the sabbath day privately, being discovered by Philip, were burnt with fire, because they made a conscience to help themselves with their hands, by reason of the religious observance of the day.
