What does Isaiah 1:10 mean?
In the previous verse (Isaiah 1:9), Isaiah compared the upcoming destruction on Judah for her rebellion against the Lord with the destruction of Sodom and Gomorrah for their sins (Genesis 18–19). The people of those cities were utterly wiped out. But God would ensure, in His grace and mercy, that a remnant of Israel would survive the coming destruction.Now Isaiah directly compares the sinfulness of the people of Judah to the sinfulness of the people of those infamous cities. He calls his audience the rulers of Sodom and the people of Gomorrah to drive home the point that their sin deserves the same destructive force.
Isaiah calls for the people of Israel to change direction before that day, to hear the word of the Lord and to give ear to God's teaching. Isaiah demands that they truly listen to what God is saying to them right now, instead of going about their daily lives as if God's judgment is not looming before them.
