'Return to Dust' in the Bible

You will eat food by the sweat of your brow until you're buried in the ground, because you were taken from it. You're made from dust and you'll return to dust."

every living thing would die all at once, and mankind would return to dust."

When you withdraw your favor, they are disappointed; Take away their breath, and they die and return to dust.

All of them go to one place: all of them originate from dust, and all of them return to dust.
