7 the LORD God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being.

Genesis 3:19 (New International Version 1984, ©1984)

19 By the sweat of your brow
   you will eat your food
until you return to the ground,
   since from it you were taken;
for dust you are
   and to dust you will return.”
