Ezekiel 38:20

“So that the fishes of the sea shall shake at my presence, &c.] From whence it appears that this great shaking shall not be on account of the army of Gog, and the devastations that it shall make; but on account of the powerful presence of God, which will be manifest in the destruction of his army: and what is here said of the shaking of the fishes of the sea, and the fowls of the heaven, and the beast of the field, and all creeping things that creep upon the earth, and all the men that are upon the earth, must be understood figuratively and hyperbolically, as Kimchi observes, and in allusion to earthquakes, which both shake and terrify all kind of creatures; the blow given to Gog will be so…”

“fishes--disturbed by the fleets which I will bring. fowls, &c.--frightened at the sight of so many men: an ideal picture. mountains--that is, the fortresses on the mountains. steep places--literally, "stairs" (Sol 2:14); steep terraces for vines on the sides of hills, to prevent the earth being washed down by the rains. every wall--of towns.”

“the fishes: Jer 4:23-26; Hos 4:3; Nah 1:4-6; Zac 14:4, Zac 14:5; Rev 6:12, Rev 6:13 steep places: or, towers, or stairs, Isa 30:25; Co2 10:4 Ezekiel 38:21”
