Genesis 3

 14 The Lord God said to the serpent,
“Because you have done this,
Cursed are you more than all cattle,
And more than every beast of the field;
On your belly you will go,
And dust you will eat
All the days of your life;
15 And I will put enmity
Between you and the woman,
And between your seed and her seed;
He shall [d]bruise you on the head,
And you shall bruise him on the heel.”
