What does Isaiah 2:10 mean?
Isaiah has been talking to the Lord (Isaiah 2:6–8), agreeing with God for rejecting His people Israel due to their sinful idol worship and unfaithfulness. Isaiah has asked the Lord not to forgive his fellow Israelites, believing their sin to be too vast and their destruction to be due (Isaiah 6:9).Now Isaiah turns and begins to write directly to the people of Israel. Mentions of "rock," in various forms, refer to people hiding in caves, stone fortresses, and other sanctuaries (Judges 20:45; 2 Samuel 22:2; Jeremiah 48:28). He tells them to hide because the Lord is coming for them. The people of Judah have refused to live in the light of the Lord (Isaiah 2:5) and now they will flee in terror from the light of His majesty when He arrives to judge them.
Paul cites this comment when writing to the church in Thessalonica (2 Thessalonians 2:9).
