'Snake's' in the Bible

Be not glad, O Philistia, all of you, because the rod which was on you is broken: for out of the snake's root will come a poison-snake, and its fruit will be a winged poison-snake.

They give birth to snake's eggs, and make spider's threads: whoever takes their eggs for food comes to his death, and the egg which is crushed becomes a poison-snake.

The wolf and the lamb will take their food together, and the lion will make a meal of grass like the ox: but dust will be the snake's food. There will be no cause of pain or destruction in all my holy mountain, says the Lord.
