Job 8:14
14 Whose support is cut off, and whose hope is no stronger than a spider's thread.
Isaiah 59:5-6
5 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.
6 Their twisted threads will not make clothing, and their works will give them nothing for covering themselves: their works are works of sin, and violent acts are in their hands.
