He that saith he is in the light, and hateth his brother, is in darkness even until now.
Anyone who claims to be in the light but hates a brother or sister is still in the darkness.
Ὁ λέγων ἐν τῷ φωτὶ εἶναι καὶ τὸν ἀδελφὸν αὐτοῦ μισῶν, ἐν τῇ σκοτίᾳ ἐστὶν ἕως ἄρτι.
O legōn en tō phōti einai kai ton adelphon aytoy misōn, en tē skotia estin eōs arti.
