Commentary
Notes on 1 John 2:4 from classic Christian and Jewish commentators (each source and its license shown beneath its notes). The classic Christian expositions comment on the surrounding passage and are grouped to its opening verse, so a note may address several verses; the Jewish commentaries on the Tanakh (Rashi and others) are per-verse, so they appear only where the commentator wrote on this verse.
