Isa 5:1-30. Parable of Jehovah's Vineyard.
A new prophecy; entire in itself. Probably delivered about the same time as the second and third chapters, in Uzziah's reign. Compare Isa 5:15, 16 with Isa 2:17; and Isa 5:1 with Isa 3:14. However, the close of the chapter alludes generally to the still distant invasion of Assyrians in a later reign (compare Isa 5:26 with Isa 7:18; and Isa 5:25 with Isa 9:12). When the time drew nigh, according to the ordinary prophetic usage, he handles the details more particularly (Isa 7:1-8:22); namely, the calamities caused by the Syro-Israelitish invasion, and subsequently by the Assyrians whom Ahaz had invited to his help.
1. to—rather, "concerning" [Gesenius], that is, in the person of My beloved, as His representative [Vitringa]. Isaiah gives a hint of the distinction and yet unity of the Divine Persons (compare He with I, Isa 5:2, 3).
of my beloved—inspired by Him; or else, a tender song [Castalio]. By a slight change of reading "a song of His love" [Houbigant]. "The Beloved" is Jehovah, the Second Person, the "Angel" of God the Father, not in His character as incarnate Messiah, but as God of the Jews (Ex 23:20, 21; 32:34; 33:14).
vineyard—(Isa 3:14; Ps 80:8, &c.). The Jewish covenant-people, separated from the nations for His glory, as the object of His peculiar care (Mt 20:1; 21:33). Jesus Christ in the "vineyard" of the New Testament Church is the same as the Old Testament Angel of the Jewish covenant.
fruitful hill—literally, "a horn" ("peak," as the Swiss shreckhorn) of the son of oil; poetically, for very fruitful. Suggestive of isolation, security, and a sunny aspect. Isaiah alludes plainly to the Song of Solomon (So 6:3; 8:11, 12), in the words "His vineyard" and "my Beloved" (compare Isa 26:20; 61:10, with So 1:4; 4:10). The transition from "branch" (Isa 4:2) to "vineyard" here is not unnatural.
