“And everything that comes from it.” This refers to everything the earth produces. Isaiah 34 transports us into the distant future and the Day of Yahweh (“the Day of the LORD”). Isaiah says that God’s judgment is going to come upon the entire earth, something we see very clearly in the book of Revelation, and so everything on earth had a vested interest in hearing what God had to say. The Day of Yahweh will be a time of horrific destruction, as many prophecies state (see commentary on Dan. 12:1).
