'Serpent's' in the Bible

“Do not rejoice, O Philistia, all of you,Because the rod that struck you is broken;For from the serpent’s root a viper will come out,And its fruit will be a flying serpent.

The wolf and the lamb will graze together, and the lion will eat straw like the ox; and dust will be the serpent’s food. They will do no evil or harm in all My holy mountain,” says the Lord.
