True Hope by Exile

Once the exile started, true hope was found only by submitting to God's plan of exile and restoration, which pointed to the true King Jesus, and His death and resurrection.
How was Ishmael, the anti-David, a warning about false hopes?

1. Ishmael faked breaking bread in unity with Babylon's appointee, and instead broke all laws of hospitality to kill him. (v.1-3)
2. Ishmael lied and faked weeping in repentance and faked placing hope in God afresh, in order to kill 70 worshippers! (v.4-9)
3. Ishmael opposed God's plan by taking captives, then escaping to join the opposing force, leaving God's people to struggle with fear and flee where there was no hope. (v.10-18)
   How can we be careful about false hopes?
   Like Judas, Ishmael betrayed someone at supper. Mt. 26:23
   How does Jesus' humility contrast Ishmael? Phil. 2:6-11.
