1 Nephi 4:2

Therefore let us go up; let us be strong like unto Moses: For he truly spake unto the waters of the Red Sea, and they divided hither and thither, and our fathers came through out of captivity on dry ground, and the armies of Pharaoh did follow and were drowned in the waters of the Red Sea.

So let’s go. Let’s be strong like Moses. He spoke to the waters of the Red Sea, and they split apart. Our ancestors walked through on dry ground. Pharaoh’s army followed them and drowned in the sea.

“So let’s go! Let’s be brave like Moses was. Remember how he spoke to the Red Sea and it split apart? Our ancestors walked through on dry ground while Pharaoh’s army drowned behind them.”
