Isaiah 51:8

for the moth shall eat them up like a garment, and the worm shall eat them like wool, bring about their destruction, put them out of the way; but My righteousness shall be forever and My salvation from generation to generation, His redemption means an eternal deliverance to all who trust in Him. Instead of continuing the comforting message from the mouth of the Lord, the prophet now, in an eminently dramatic manner introduces the listening believers as speaking, their prayer serving to substantiate the statements which have just been made.
