What does Isaiah 22:12 mean?
What do you do when the enemy horde is at your doorstep? Isaiah has described the arrival of the Assyrians or Babylonians coming to destroy Jerusalem (Isaiah 22:5). The valleys are full of their chariots. The enemy horsemen are right outside the gates (Isaiah 22:6–7). By every human measure, the people inside the gates would assume that the situation was dire. They could not defeat the overwhelming force just on the other side of the wall.The Lord God of hosts knew what His people should do in that moment: They should repent and ask Him for help. His people should express their fear to Him in sorrow and trembling. They should demonstrate their mourning and sadness to each other by shaving their heads, or tearing their hair out, and by wearing sackcloth. This was an understood cultural display of extreme grief at this point in history.
In short, the Lord wanted His people to take advantage of this moment when all other hope was lost to put their full hope in Him. He wanted His people to finally rely on Him. Instead, they relied on themselves by shoring up the city's defenses as best they could and then partied like there would be no tomorrow (Isaiah 22:13).
