Jamieson, Fausset and Brown on Ezekiel 36:35

35. they shall say--The heathen, who once made Israel's desolation a ground of reproach against the name of Jehovah Himself (Eze 36:20, 21); but now He so vindicates its sanctity (Eze 36:22, 23) that these same heathen are constrained to acknowledge Israel's more than renewed blessedness to be God's own work, and a ground for glorifying His name (Eze 36:36).

Eden--as Tyre (the type of the world powers in general: so Assyria, a cedar "in the garden of God, Eden," Eze 31:8, 9), in original advantages, had been compared to "Eden, the garden of God" (Eze 28:13), from which she had fallen irrecoverably; so Israel, once desolate, is to be as "the garden of Eden" (Is 51:3), and is to be so unchangeably.
