Jah is a word that refers to God, usually in the Rastafarian religion. When people say "Jah," they are talking about God and their belief in a higher power that is all-knowing and all-powerful. It is a way to show respect and reverence for God. For Rastafarians, Jah is the guiding force in their lives and provides them with strength and purpose. The word "Jah" can also be used in music and art, often in reggae music, to express spirituality and belief in a higher power.
