Context Reading
19Moses took the bones of Joseph with him, for he had made the children of Israel swear, saying, “God will surely visit you, and you shall carry up my bones away from here with you.” 20They took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. 21Yahweh went before them by day in a pillar of cloud, to lead them on their way, and by night in a pillar of fire, to give them light, that they might go by day and by night: 22the pillar of cloud by day, and the pillar of fire by night, didn’t depart from before the people.
