Isaiah 55:3-4
3. me . . . live—by coming to me ye shall live: for "I am the life" (Joh 14:6).
everlasting covenant— (Jer 32:40; 2Sa 23:5). with you . . . David—God's covenant is with the antitypical David, Messiah (Eze 34:23), and so with us by our identification with Him. sure—answering to "everlasting," irrevocable, unfailing, to be relied on (Ps 89:2-4, 28, 29, 34-36; Jer 33:20, 21; 2Sa 7:15, 16; 2Co 1:18-20). mercies of David—the mercies of grace (Isa 63:7; Joh 1:16) which I covenanted to give to David, and especially to Messiah, his antitype. Quoted in Ac 13:34.4. him—the mystical David (Eze 37:24, 25; Jer 30:9; Ho 3:5). Given by God (Isa 49:6).
witness—He bore witness even unto death for God, to His law, claims, and plan of redeeming love (Joh 18:37; Re 1:5). Revelation is a "testimony"; because it is propounded to be received on the authority of the Giver, and not merely because it can be proved by arguments. commander—"preceptor" [HORSLEY]; "lawgiver" [BARNES]. to the people—rather, "peoples."Jeremiah 30:9
9. Instead of serving strangers (Jer 30:8), they shall serve the Lord, their rightful King in the theocracy (Eze 21:27).
David, their king—No king of David's seed has held the scepter since the captivity; for Zerubbabel, though of David's line, never claimed the title of "king." The Son of David, Messiah, must therefore be meant; so the Targum (compare Isa 55:3, 4; Eze 34:23, 24; 37:24; Ho 3:5; Ro 11:25-32). He was appointed to the throne of David (Isa 9:7; Lu 1:32). He is here joined with Jehovah as claiming equal allegiance. God is our "King," only when we are subject to Christ; God rules us not immediately, but through His Son (Joh 5:22, 23, 27). raise up—applied to the judges whom God raised up as deliverers of Israel out of the hand of its oppressors (Jud 2:16; 3:9). So Christ was raised up as the antitypical Deliverer (Ps 2:6; Lu 1:69; Ac 2:30; 13:23).Ezekiel 34:23-24
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 3:5.24. my servant—implying fitness for ruling in the name of God, not pursuing a self-chosen course, as other kings, but acting as the faithful administrator of the will of God; Messiah realized fully this character (Ps 40:7, 8; Isa 42:1; 49:3, 6; 53:11; Php 2:7), which David typically and partially represented (Ac 13:36); so He is the fittest person to wield the world scepter, abused by all the world kings (Da 2:34, 35, 44, 45).
Ezekiel 37:24-25
24. David—Messiah (See on Eze 34:23, 24).
25. for ever— (Isa 60:21; Joe 3:20; Am 9:15).
