Chapter XIV.—How Jesus Delivered James from the Bite of a Serpent.

And Joseph sent James to gather straw, and Jesus followed him.  And while James was gathering the straw, a viper bit him; and he fell to the ground, as if dead from the poison.  And Jesus seeing this, blew upon his wound; and immediately James was made whole, and the viper died.
