For “God has put everything under His feet.” Now when it says that everything has been put under Him, this clearly does not include the One who put everything under Him.
KJV
For he hath put all things under his feet. But when he saith, all things are put under [him, it is] manifest that he is excepted, which did put all things under him.
ASV
For, He put all things in subjection under his feet. But when he saith, All things are put in subjection, it is evident that he is excepted who did subject all things unto him.
