The Lord is the dependable cornerstone in Jerusalem, a valuable foundation stone of God's true city. There would be real hope in Jerusalem if the leaders and people turned to Him. By trusting in God, they would be safe during the worst storm or earthquake (see Isaiah 8:14; Psalm 118:22; Matthew 7:24–27; 21:42; see the application to Jesus Christ, Romans 9:33; 10:11; 1 Corinthians 3:11; Ephesians 2:20; 1 Peter 2:4–7).
