'Depths of the Earth' in the Bible

But those who seek to destroy my lifewill go into the depths of the earth.

You caused me to experiencemany troubles and misfortunes,but You will revive me again.You will bring me up again,even from the depths of the earth.

The depths of the earth are in His hand,and the mountain peaks are His.

My bones were not hidden from Youwhen I was made in secret,when I was formed in the depths of the earth.
