Acts 21:21

κατηχήθησαν : the word seems to imply definite instruction, not merely audierunt, Vulgate. Hort refers to the term as implying here assiduous talking and lecturing, Judaistic Christianity, p. 107. ἀποστασίαν, cf. Malachi 2:15; Malachi 2:15 (ἀπόστασιν) when the officers of Antiochus Epiphanes, in the time of Mattathias, tried to compel the people of Modin to forsake the law and to sacrifice upon the idol altar. μὴ περιτέμνειν : these words and those which follow were an entire perversion of St. Paul's teaching, just as his enemies gave a perverted view of the Apostle's supposed intrusion with Trophimus into the temple, Acts 21:29. The exemption from the Mosaic law was confined to Jewish converts, Acts 16:3; 1 Corinthians 7:18. τοῖς ἔθεσι, cf. Acts 6:14; Acts 15:1. περιπατεῖν : only here in Luke, but often in the Epistles in this sense, cf. Mark 7:5.
