What does Isaiah 5:3 mean?
This parable started as if it were a love song (Isaiah 5:1). Isaiah describes how his beloved did all the hard work to develop a vineyard only to discover in the end that the grapes were sour and worthless for their purpose (Isaiah 5:2).Now Isaiah shifts to the voice of the vineyard-maker. He calls out to his audience to ask them to weigh in on the matter. He will ask if there was anything he could have done differently to receive a different result (Isaiah 5:4). This is a rhetorical question, of course, meant to point out that the Master is not the problem.
