And I will set up one shepherd over them, and he shall feed them, even my servant {k} David; he shall feed them, and he shall be their shepherd.

(k) Meaning Christ, of whom David was a figure, See Geneva Jer 30:9 See Geneva Ho 3:5

Wesley's Notes

34:23 One shepherd - Christ, the great good, chief, only shepherd, that laid down his life for his sheep. My servant David - The seed of David, the beloved one, who was typified by David, and is in other places called by his name, as Jer 30:9 Eze 37:24 Isa 37:35 Hos 3:5. He shall feed - Do all the office of a good and faithful shepherd, and that for ever.

Jamieson-Fausset-Brown Bible Commentary

23. set up-that is, raise up by divine appointment; alluding to the declaration of God to David, "I will set up thy seed after thee" (2Sa 7:12); and, "Yet have I set My king on My holy hill of Zion" (Ps 2:6; compare Ac 2:30; 13:23).

one shepherd-literally, "a Shepherd, one": singularly and pre-eminently one: the only one of His kind, to whom none is comparable (So 5:10). The Lord Jesus refers to this prophecy (Joh 10:14), "I am THE Good Shepherd." Also "one" as uniting in one the heretofore divided kingdoms of Israel and Judah, and also "gathering together in one all things in Christ, both which are in heaven and on earth" (Eph 1:10); thus healing worse breaches than that between Israel and Judah (Col 1:20). "God by Him reconciling all things unto Himself, whether things in earth or in heaven."

David-the antitypical David, Messiah, of the seed of David, which no other king after the captivity was: who was fully, what David was only in a degree, "the man after God's own heart." Also, David means beloved: Messiah was truly God's beloved Son (Isa 42:1; Mt 3:17). Shepherd means King, rather than religious instructor; in this pre-eminently He was the true David, who was the Shepherd King (Lu 1:32, 33). Messiah is called "David" in Isa 55:3, 4; Jer 30:9; Ho 3:5.

Matthew Henry's Concise Commentary

34:17-31 The whole nation seemed to be the Lord's flock, yet they were very different characters; but he knew how to distinguish between them. By good pastures and deep waters, are meant the pure word of God and the dispensing of justice. The latter verses, 23-31, prophesy of Christ, and of the most glorious times of his church on earth. Under Him, as the good Shepherd, the church would be a blessing to all around. Christ, though excellent in himself, was as a tender plant out of a dry ground. Being the Tree of life, bearing all the fruits of salvation, he yields spiritual food to the souls of his people. Our constant desire and prayer should be, that there may be showers of blessings in every place where the truth of Christ is preached; and that all who profess the gospel may be filled with fruits of righteousness.
