Isa 51:9-11

9Awake, awake, put on strength, O arm of the Lord! Awake, as in days of old, the generations of long ago! Was it not you who cut Rahab in pieces, who pierced the dragon?10Was it not you who dried up the sea, the waters of the great deep; who made the depths of the sea a way for the redeemed to cross over?11So the ransomed of the Lord shall return, and come to Zion with singing; everlasting joy shall be upon their heads; they shall obtain joy and gladness, and sorrow and sighing shall flee away.
