“I will now sing for my beloved the song of my beloved about his vineyard; my beloved had a vineyard in a fertile corner (Isaiah 5:1).” Isaiah, along with all of the more lyrical prophets, uses a great deal of metaphor in the text. So I’m not entirely sure what the subtext is to these words, and what the beloved and the vineyard are meant to represent. The vineyard, whatever it means beneath the surface, produces wild berries. So the speaker asks the people of Jerusalem to judge the vineyard, to figure out why this oddity occurred. The vineyard owner will abandon his fields, and no longer take care of them as a result. “For the vineyard of the Lord of Hosts is the House of Israel, and the people of Judah are the plant of His joy; and He hoped for justice, and, behold, there was injustice; for righteousness, and behold, an outcry (Isaiah 5:7).” Looks like we know that the vineyard is supposed to represent!
The people don’t respect God, as has been an ongoing lament in the last few books. Therefore, they’re going to be sent into exile, and many will die. “And man shall be humbled, and man shall be brought low, and the eyes of the haughty shall be brought low (Isaiah 5:15).”
