Albert Barnes Commentary Ezekiel 17:22

"Thus saith the Lord Jehovah: I will also take of the lofty top of the cedar, and will set it; I will crop off from the topmost of its young twigs a tender one, and I will plant it upon a high and lofty mountain:" — Ezekiel 17:22 (ASV)

A contrast between the dealings of Nebuchadnezzar and Yahweh. Nebuchadnezzar “cut off,” Yahweh will “set up” the topshoot; Nebuchadnezzar “carried it into a land of traffic,” Yahweh will “plant it in the mountain of the height of Israel.” Nebuchadnezzar set his favorite as a “vine, lowly” though not poor, in the place where such trees as the humble “willow” grow and thrive. Yahweh’s favorite is like the “lofty cedar, eminent upon a high mountain.”

The highest branch of the high cedar - The rightful representative of the royal house of David, the Messiah.

Tender one - The Messiah. This prophecy rests upon Isaiah 11:1, Isaiah 11:10.
