'Steep' in the Bible

so that the fish of the sea, and the fowl of the heavens, and the beasts of the field, and all creeping things which creep upon the earth, and all mankind that are upon the face of the earth shall shake at my presence; and the mountains shall be thrown down, and the steep places shall fall, and every wall shall fall to the ground.

And the mountains shall be melted under him, and the valleys shall be cleft, as wax before the fire, as waters poured down a steep place.
