What does Isaiah 26:20 mean?
The previous verse (Isaiah 26:19) gives the reader a glimpse into an astonishing moment. In the end times, after the Lord has secured His victory, He will raise His people who have died back to life. They will rejoice in their Lord. Death is not the end of the story for the people of God.This next part of the chapter shows Isaiah telling his people to hide for a while. Why? The storm of the Lord's fury in judgment against all the wickedness in the world is about to hit with enormous force. It is not the Lord's intent to hammer His own people in His fury. Instead, the Lord will punish the people of the earth for their sin (Isaiah 26:21).
Some read this verse as instruction to future believers to hide when the time of the Lord's judgment comes. One interpretation is that those believers are to trust God to spare them from His punishment bestowed on those who rejected Christ. Another possible reading is that Isaiah is telling the Israelites of his time that it is acceptable to enter their tombs, their "chambers," and hide away during the time of the Lord's fury. This would suggest that the people of His time can hide with full confidence that they will be resurrected in the end, after the judgment has passed.
