Jah
Jah is the name used for 
God in the 
religious movement of 
Rastafarianism. It is a shortened form of the name 
Yahweh (
Jahwe) or 
Jehovah, and is 
transliterated "Jah" in a single instance (
Psalm 68:4) in the 
King James Version of the 
Bible.
Some authors, particularly Burning Spear use for this purpose a term This Man.
The word Jah-Man is used for one Rastafarian among them.
Jah is also an alternative spelling of the name of the Egyptian deity "Joh".
