Isaiah 5:2

5:2 He built a hedge around it, removed its stones,

and planted a vine.

He built a tower in the middle of it,

and constructed a winepress.

He waited for it to produce edible grapes,

but it produced sour ones instead.

Isaiah 5:4

5:4 What more can I do for my vineyard

beyond what I have already done?

When I waited for it to produce edible grapes,

why did it produce sour ones instead?
