But to which of the angels. — The final appeal is made to that Psalm which more frequently than any other is quoted in reference to Christ, and which we have already seen to be the source of all the New Testament references to the Saviour’s session at the right hand of God. It is not necessary to say much here respecting Psalms 110, to which so many allusions will be made in the course of this Epistle. That it was regularly understood by the Jews of our Lord’s time to be a Messianic Psalm is clear both from Matthew 22:43-44, and from the independent notices which we possess. Most probably, it stands alone amongst the Psalms as being simply prophetic: the words of Hebrews 1:1 have never been addressed either to angels or to an earthly king. On the special words of the quotation see Hebrews 1:3.

Until I make... — Literally, until I shall have made Thine enemies a footstool of Thy feet.
