Question: where in the bible does it say ashes to ashes dust to dust?
Answer: 'Ashes to ashes' derives from the English Burial Service. The text of that service is adapted from the Biblical text, Genesis 3:19 (King James Version): In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
