Isaiah 51:12

10 Was it not You who dried up the sea, the waters of the great deep, who made a road in the depths of the sea for the redeemed to cross over?

11 So the redeemed of the LORD will return and enter Zion with singing, crowned with everlasting joy. Gladness and joy will overtake them, and sorrow and sighing will flee.

“I, even I, am He who comforts you. Why should you be afraid of mortal man, of a son of man who withers like grass?

13 But you have forgotten the LORD, your Maker, who stretched out the heavens and laid the foundations of the earth. You live in terror all day long because of the fury of the oppressor who is bent on destruction. But where is the fury of the oppressor?

14 The captive will soon be freed; he will not die in the dungeon, and his bread will not be lacking.

Do read the surrounding verses too, because the context often says more than a single verse.
