A.T. Robertson Commentary Ephesians 4:10

"He that descended is the same also that ascended far above all the heavens, that he might fill all things.)" — Ephesians 4:10 (ASV)

Is the same also (αυτος εστιν). Rather, "the one who came down (ο καταβας, the Incarnation) is himself also the one who ascended (ο αναβας, the Ascension)."

Far above (υπερανω). See 1:21.

All the heavens (παντων των ουρανων). Ablative case after υπερανω. For the plural used of Christ's ascent see Heb 4:14; 7:27. Whether Paul has in mind the Jewish notion of a graded heaven like the third heaven in 2 Corinthians 12:2 or the seven heavens idea one does not know.

That he might fill all things (ινα πληρωση τα παντα). This purpose we can understand, the supremacy of Christ (Colossians 2:9f.).
