Adam Clarke on Philippians 2:10

That at the name of Jesus every knee should how - That all human beings should consider themselves redeemed unto God by his blood, and look for an application of this redemption price; and that all who are saved from their sin should acknowledge him the author of their salvation. In a word, that παν επουρανιων, all the spirits of just men made perfect, now in a state of blessedness; και επιγειων, all human beings still in their state of probation on earth; και καταχθονιων, and all that are in the shades below, who have, through their own fault, died without having received his salvation; should acknowledge him.
