Jamieson, Fausset and Brown on Philippians 2:10

10. at the name--rather as Greek, "in the name."

bow--rather, "bend," in token of worship. Referring to Is 45:23; quoted also in Ro 14:11. To worship "in the name of Jesus," is to worship Jesus Himself (compare Php 2:11; Pr 18:10), or God in Christ (Joh 16:23; Ep 3:14). Compare "Whosoever shall call upon the name of the Lord (that is, whosoever shall call on the Lord in His revealed character) shall be saved" (Ro 10:13; 1Co 1:2); "all that call upon the name of Jesus Christ our Lord" (compare 2Ti 2:22); "call on the Lord"; Ac 7:59, "calling upon ... and saying, Lord Jesus" (Ac 9:14, 21; 22:16).

of things in heaven--angels. They worship Him not only as God, but as the ascended God-man, "Jesus" (Ep 1:21; He 1:6; 1Pe 3:22).

in earth--men; among whom He tabernacled for a time.

under the earth--the dead; among whom He was numbered once (Ro 14:9, 11; Ep 4:9, 10; Re 5:13). The demons and the lost may be included indirectly, as even they give homage, though one of fear, not love, to Jesus (Mr 3:11; Lu 8:31; Jas 2:19, see on Php 2:11).
