'Serpent's' in the Bible

And {an infant} shall play over a serpent's hole, and {a toddler} shall put his hand on a viper's hole.

[The] wolf and [the] lamb shall feed like one, and [the] lion shall eat straw like the ox, but dust [shall be] [the] serpent's food. They shall do no evil, and they shall not destroy on all {my holy mountain}," says Yahweh.
