Isaiah 63:11-13

11Then they remembered past years, when Moses led their ancestors out of Egypt. They said, ‘Where is the Lord now, when we need him? He brought his people safely through the sea, with Moses as their leader. He caused his Holy Spirit to work among them.

12He caused his power to be with Moses, as Moses raised his arm over the sea. He caused the waters to become separate so that his people could go across. In that way, he caused his name always to be famous.

13He led them through the deep water of the sea. They ran across like horses on open ground, and they did not fall.
