28 The like doctrine you have also in the interpretation of the Stone, which was cut out of a mountain without hands, which is Christ according to the flesh; And His kingdom shall not be left to another people. David also says in one place, Your throne, O God, is for ever and ever; and in another place, You, Lord, in the beginning hast laid the foundations of the earth, etc., they shall perish, but You remain, etc.; but You are the same, and Your years shall not fail: words which Paul has interpreted of the Son.
