Isaiah, as a folk singer, sang a parable about a vineyard that compared Israel to a vineyard that Yahweh had planted and from which He legitimately expected to receive fruit.57However, the prophet's original audience did not realize what this song was about at first. It started out sounding like a happy wedding song, but it turned out to be a funeral dirge announcing Israel's death. This chiastic "song"is only the first part of Isaiah's unified message in this chapter. His song flowed into a sermon.
"In a way similar to Nathan's, when he used a story to get King David to condemn his own action (2 Sam. 12:1-7), so Isaiah sets his hearers up to judge themselves . . ."58
5:1-2 Isaiah offered to sing a song for his good friend about his friend's "vineyard,"a figure for one's bride (cf. Song of Sol. 1:6; 8:12). Really this song contains a harsh message about another person and his "vineyard,"namely, Yahweh and Israel. Isaiah painted a picture of a man cultivating his relationship with his wife only to have her turn out disappointing. But, as would shortly become clear, he was really describing God's careful preparation of Israel to bring forth spiritual fruit. The man double-fenced his vineyard and built a watchtower and a wine vat (storage tank) in it indicating that He intended it to satisfy him for a long time. Yet all His work was for naught; His vines disappointed Him. Ezekiel observed that if a vine does not produce fruit, it is good for nothing (Ezek. 15:2-5).
5:3-4 Isaiah next appealed to his audience, the people of Jerusalem and Judah, speaking for his well-beloved (God). He asked them for their opinion. What more could he have done to insure a good crop? Why did his vines produce worthless (sour) grapes? In view of what the owner had done (vv. 1-2), the answers would have to be, You could have done nothing more than you did, and, The grapes were the cause of the disappointment, not you.
5:5-6 The well-beloved explained what he would do to his disappointing vineyard. He would stop protecting it and abandon it to the elements and to its enemies. He would invest no more labor on it and would even stop providing it with the nourishment it needed to flourish. He would even assist in its destruction. This sounded like another Hosea and Gomer story.
5:7 Isaiah now shocked his audience by identifying the characters in his parable by name. His well-beloved and the owner of the vineyard was Yahweh of hosts, not some unnamed friend; the vineyard was Israel, not his friend's wife (cf. 1:8; 3:14; Ps. 80:8-18; Jer. 2:21; 12:10; Ezek. 15:6-8; Hos. 10:1; Matt. 21:33-44); and the Judahites were the individual plants in this unresponsive vineyard.
"Before the fall of Samaria in 722 BC the house of Israelmeant either the whole divided nation or its northern component. The prophets did not countenance the division, and whether specifically called to prophesy to north or south they tended to embrace the whole in their ministry (cf. Am. 3:1). Isaiah thus addresses the whole nation and then narrows his vision to the specially privileged men of Judah . . ."59
The good fruit God looked for was justice (the righting of wrongs) and righteousness (right relationships), but the bad fruit the vines produced was oppression (the inflicting of wrongs) and violence (wrong relationships; cf. 60:21; 61:3).60
As the vineyard disappointed the Lord, so this song disappointed its original hearers. It proved to be confrontation, not entertainment.
