Atharva Veda 6.56: A charm against snakes

Let not the serpent slay us, O Gods, with our children and our folk.
Let it not close the opened mouth nor open that which now is closed.

Be worship paid unto the black, worship to that with stripes across!
To the brown viper reverence, reverence to the demon brood!

I close together fangs with fang, I close together jaws with jaw.
I close together tongue with tongue, I close together mouth with mouth.
