As if a man fled from a lion, and a bear met him; or went into the house, and leaned his hand on the wall, and a serpent bit him.

Be ye not as the horse, or as the mule, which have no understanding: whose mouth must be held in with bit and bridle, lest they come near to thee.

And the LORD sent fiery serpents among the people, and they bit the people; and many people of Israel died.
