'Steep' in the Bible

so that the fishes of the sea, the birds of the sky, the animals of the field, all the creatures that crawl on the earth, and all the men that are on the face of the earth will tremble and shake at My presence; the mountains will crumble, the steep places will fall, and every wall will fall to the ground.

The mountains shall melt under HimAnd the valleys shall be splitLike wax before the fire,Like waters poured down a steep place.

Wail, O cypress, for the cedar has fallen,Because the magnificent trees have been destroyed;Wail, O oaks of Bashan,For the inaccessible forest [on the steep mountainside] has come down.
