After the desolation of the city, Isaiah holds out the hope that there will be a remnant left, pictured as the gleanings of olives and grapes (Isaiah 24:13). The following verse suddenly uses third person plural verbs: “they raise voices, they shout, they cry.” The only evident antecedent is the grapes and olives of the previous voice. Singing grapes and olives, like Veggie Tales with fruit.

And they sing about the “excellence” of Yahweh, just like Israel did after they crossed the Red Sea (Exodus 15:7; ga’on ). And they raise their voices from the “sea” (Isaiah 24:15; yam , sometimes translated as “west”). That is, the singing olives and grapes have just been through an exodus.

And that suggests that the exodus is itself a kind of harvest. After shaking the olive tree and vine of Egypt, Yahweh gathered up the gleanings and carried them off to plant them in a new land of wine and oil.
