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.
And when all things have been subjected to Him, then the Son Himself will be made subject to Him who put all things under Him, so that God may be all in all.
KJV
And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
ASV
And when all things have been subjected unto him, then shall the Son also himself be subjected to him that did subject all things unto him, that God may be all in all.
