A.T. Robertson Commentary Ephesians 5:9

"(for the fruit of the light is in all goodness and righteousness and truth)," — Ephesians 5:9 (ASV)

The fruit of light (ο καρπος του φωτος). Two metaphors (fruit, light) combined. See Ga 5:22 for "the fruit of the Spirit." The late MSS. have "spirit" here in place of "light."

Goodness (αγαθοσυνη). Late and rare word from αγαθος. See 2 Thessalonians 1:11; Galatians 5:22.
