Isaiah 51:9-10

9 Awake, 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?
10 Was 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?
