The Emphasised Bible
also called Rotherham Version
1902 by Joseph Rotherham
It is written:
Sheol and Abaddon are before Most High: How much more then the hearts of the children of men!
Sheol and Abaddon are never satisfied; And the eyes of man are never satisfied.
Sheol is naked before `God', And Abaddon hath no covering.
