Philippians 2:10

That in the name of Jesus every knee should bow

(ινα εν τω ονοματ Ιησου παν γονυ καμψη). First aorist active subjunctive of καμπτω, old verb, to bend, to bow, in purpose clause with ινα. Not perfunctory genuflections whenever the name of Jesus is mentioned, but universal acknowledgment of the majesty and power of Jesus who carries his human name and nature to heaven. This universal homage to Jesus is seen in Romans 8:22; Ephesians 1:20-22 and in particular Revelation 5:13.Under the earth

(καταχθονιων). Homeric adjective for departed souls, subterranean, simply the dead. Here only in the N.T.
