For behold, I will make you small among the nations,
despised among mankind.
The horror you inspire has deceived you,
and the pride of your heart,
you who live in the clefts of Sela,
who hold the height of the hill.
Though you make your nest as high as the eagle's,
I will bring you down from there,
declares the Lord.
Jeremiah 49:15-16

Sela was the capital of Edom, a high, rocky place.
Also see Obadiah 1:3-4.
