Isaiah 26:1-27; 27:1
"You will keep the mind that is dependent on You in perfect peace, for it is trusting in You. 4 Trust in the Lord forever, because in Yah, the Lord, is an everlasting rock!" (Isa 26:3-4, HCSB).
Isaiah 24 is a general summary. All nations will be destroyed (Isa 24:1-3) and her drunken songs silenced (Isa 24:7-9), because the Lord alone will be exalted in that day (Isa 24:3). In Isaiah 25, God is going to have a feast on his great holy mountain (Isa 25:6). It is a feast for the whole world, for "all peoples." This is hyperbole here: the whole world is destroyed, and the whole world will be saved. No one escapes judgment, and everyone has the possibility of redemption. God will pull away the shroud that covers humanity (Isa 25:6). God will raise us from the dead. We will have songs in the night because of what he has done (Isa 25:9). But the arrogant will not escape. Proud and arrogant Moab will be pushed down into a manure pile (Isa 25:10). Isaiah 26-27 continues the thought of 24-25, such as the song of joy (Isa 26:1, 19; 27:2), because of God's victory over the city of oppression (Isa 26:5; 27:10, 13), but with a somewhat changed focus. Whereas ch. 24-25 focus on the victory and the feast which follows, ch. 26-27 reflect in a somewhat more solemn view upon the meaning of this victory for Judah. However, the general theme of God's sovereignty remains of central importance as does the atmosphere of hope stemming from that conviction.
