Psalms 80:17,18 - Joseph Benson’s Commentary on the Old and New Testaments

Let thy hand Thy power, to protect and strengthen him; be upon the man of thy right hand That king (whoever he was) of the house of David, that was now to rule and go in and out before them. He calls him the man of God's right hand, because he was the representative of their state, which was dear to God, as a man's right hand is dear to himself, and as Benjamin, whose name signifies the son of the right hand, was dear to his father Jacob; and because he was president in their affairs, and an instrument in God's right hand of much good to them, defending them from themselves, and from their enemies, and directing them in the right way; and was under-shepherd to him who was the great Shepherd of Israel. Upon the son of man That king of David's race, just mentioned, in whose safety and prosperity he considered the welfare and happiness of the whole kingdom as being involved; whom thou madest strong for thyself That is, to serve the interest of thy kingdom among men. So will we not go back from thee This glorious favour of thine will oblige us to love and serve thee, and trust in thee so long as we have a being, and will preserve us from relapsing into idolatry and wickedness, as we have too often done. Quicken us Revive and restore us to our former tranquillity and happiness; revive our dying interests, and our drooping spirits, and we will call upon thy name We shall be encouraged, and will continue to do so upon all occasions, having found, by experience, that it is not in vain. But many interpreters, both Jewish and Christian, apply this to the Messiah, the Son of David, the protector and Saviour of the church, and the keeper of the vineyard. He is the man of God's right hand; to whom he has sworn by his right hand, as the Chaldee interprets it; whom he has exalted to his right hand, and who is indeed the right hand and arm of the Lord, invested with all power in heaven and on earth. And he is that Son of man whom the Father made strong for himself for the glorifying of his name, and the advancing of the interests of his kingdom among men. God's hand was upon him throughout his whole undertaking, to support and strengthen, to protect and animate him, that the good pleasure of the Lord might prosper in his hand. And the stability and constancy of believers, in his work and service, are owing to his grace upholding and strengthening them.
