Jamieson, Fausset & Brown

As in Psa 45:6 the divine nature is made prominent, here the moral qualities of the human are alleged as the reason or ground of the mediatorial exultation. Some render "O God, thy God," instead of God, thy God--but the latter is sustained by the same form (Psa 50:7), and it was only of His human nature that the anointing could be predicated (compare Isa 61:3). oil of gladness--or token of gladness, as used in feasts and other times of solemn joy (compare Kg1 1:39-40). fellows--other kings.
