 After the Israelites escape from the midst of the sea, Yahweh causes the ocean to close back in on the pursuing Egyptian army, drowning them to death.In the desert Yahweh feeds them with manna that accumulates on the ground with the morning dew.They are led by a column of cloud, which ignites at night and becomes a pillar of fire to illuminate the way, southward through the desert until they come to Mount Sinai.
