Dust You Shall Eat - Genesis 3:14

Genesis 3:14 ESV 

The Lord God said to the serpent, 

“Because you have done this,

cursed are you above all livestock

and above all beasts of the field;

on your belly you shall go,

and dust you shall eat

all the days of your life.

Genesis 3:19

By the sweat of your face

you shall eat bread,

till you return to the ground,

for out of it you were taken;

for you are dust,

and to dust you shall return.”

The serpent is cursed to eat dust all the days of its life. Adam is cursed to return to dust, which is food for the serpent. 

Both fall to the ground for their transgression. Adam to work the ground instead of the garden and the serpent to slither on its belly on that ground as an enemy of man. 

Later Jesus would provide the way for man to rise from that dust to the the kingdom of heaven as a new creature. The dust is left behind, but there is plenty left for the serpent.
