Psalms 78:13-15

¹³Then he caused the Red Sea to divide, causing the water on each side to pile up like a wall, with the result that our ancestors walked through it on dry ground.

¹⁴He led them by a bright cloud during the day and by a fiery light during the night.

¹⁵He split rocks open in the desert, giving to our ancestors plenty of water from deep inside the earth.
