Isaiah 33:20 - Coke's Commentary on the Holy Bible

Look upon Zion— The prophet here, representing the chorus of teachers comforting the people of God, commands this people to turn their attention to Jerusalem, after its restoration flourishing greatly; and promises to them the durable stability of that state, under the metaphor of a tent sustaining itself by stakes and cords against winds and storms, and affording a safe and secure shelter to those within it. In this passage he is generally thought to refer to the spiritual Jerusalem; that is to say, to the church of the New Testament, which should be the last dispensation of grace. At least, if the state of Jerusalem under the Maccabees be referred to in the letter, there can be no doubt of its secondary and typical reference to the church of Jesus Christ, founded on the day of Pentecost.
