Charles H. Spurgeon on Psalms 80:17

The man of thy right hand... The Son of Man. These striking expressions apply in the fullest and most perfect sense to Christ. If the Man of God's right hand be the man placed there, to whom can the title apply but to him? for, to which of the angels said God at any time, Sit thou on my right hand? Heb 1:5; and much less has he said this of any Jewish king. As to the other appellation, The Son of Man, it is one of Christ's most definite titles, being given to him in Scripture no less than seventy-one times; in sixty-seven instances by himself; once by Daniel; once by the martyr Stephen; and twice by the Apostle John in the Revelation. He it is, too, whom the Father has made strong for the salvation of his church, and who will yet turn away captivity from the chosen people, and restore them to a place in the church, so that henceforth they will not go back from God.
