Yahweh Judges the Rulers. Probably an independent oracle, presumably, though not certainly, uttered early in Isaiah's career. Yahweh has taken up the cause of the wronged, and calls elders and princes to account. They are the keepers of the vineyard (Isaiah 5:1-7), but they have abused their position to their own profit; they crush Yahweh's people, and grind between the millstones the faces of the poor.
Isaiah 3:13. Isaiah would hardly speak of a judgment of the nations. Read his people (LXX).
