God tells Ezekiel to repeat an allegory to the house of Israel.
In the allegory, a great eagle takes the topmost shoot from the tallest cedar in Lebanon.
The eagle drops into a city of merchants, and then plants a seed in the land from which he took the shoot.
The seed grows into a vine which stretches out towards another great eagle. The vine wants the eagle to water the seed and transplant it in good soil so that the vine becomes a noble vine.
God asks if this will really happen to the vine. Won't it just get pulled up and die? Hint: yes.
Finally, God explains the allegory. The King of Babylon is the first eagle who exiles king Jehoiachin (the shoot from the cedar).
He then plants Zedekiah like the seed to rule over Judah, believing he'll stay allied with Babylon.
But Zedekiah (the vine) reaches out towards Egypt, the second eagle, hoping it'll become his ally.
As punishment for breaking this covenant with Babylon, Zedekiah will end up dying in exile in Babylon.
The Judean troops and survivors will all be scattered throughout the land.
But God predicts a positive future for his people: he'll pick a shoot from the cedar (the House of David) and place it on top of the mountain of Israel, where it'll grow into a noble tree and give shelter to birds and bear fruit.
The other trees of the field (nations) will know that God is the lord.
God says that he makes the high tree low, the low tree high, dries up the green tree, and makes the dry tree flourish. Guy's got a way with words.
