Charles Ellicott Commentary Ezekiel 31:8

"The cedars in the garden of God could not hide it; the fir-trees were not like its boughs, and the plane-trees were not as its branches; nor was any tree in the garden of God like unto it in its beauty." — Ezekiel 31:8 (ASV)

The garden of God.— See Ezekiel 31:9; Ezekiel 31:16; Ezekiel 31:18; also Ezekiel 28:13. This is not a representation of Assyria as being in the garden of God, as in the case of Tyre in Ezekiel 28:13, but only a further expression of its greatness by a comparison of the tree representing it with the trees of Paradise. Yet this comparison may have been suggested by the fact that the traditional site of Eden was within the bounds of the Assyrian Empire. Fir trees are generally understood to be cypresses, and chestnut to be plane-trees.
