The Crossing of the Red Sea. For three days and nights God led them by a pillar of cloud by day and of fire by night. At the end of the third day they had reached the shore of the Red Sea and were shut in by mountains on each side. They were greatly frightened to find that Pharaoh with a host of chariot-warriors was in close pursuit of them. But God caused the cloud that had been leading them to remove to their rear and to throw a shadow upon their enemies while giving power to the east wind (Ex. 14:21) that caused the waters of the sea to divide so they could cross on dry ground. When Pharaoh and his hosts attempted to follow then. God caused the waters to return and overwhelm them. As in former miracles, Moses was God's instrument in performing this miracle. When they were safe across and saw the overthrow of their enemies their feelings of joy expressed themselves in a great song of victory in which they ascribe praise to God and recount the incidents of his work of deliverance. The Journey to Sinai. It is not possible to locate all the stations at which they stopped on their journey from the Red Sea to the time of their encampment at the foot of Horeb or Sinai. The list is given in Numbers, Chapter thirty-three. For our purpose it is sufficient to notice only a few places and incidents of the journey. (1) They encamped at Marah, being the first watering place they had found. The water, however, was bitter and could not be used until God had enabled Moses by a miracle to sweeten it. This was the first example of divine support for them. (2) At Elim they found water and shade and here God gave them the manna from heaven and the quail at eventide. Thus again Jehovah demonstrated his purpose to provide for their needs while wandering through the wilderness. This food was supplied to them continuously until they reached Canaan forty years later. (3) Under the leadership of the cloud, which during all the forty years of wilderness wandering, was their guide, they next encamped at Rephidim where there was no water at all. Here Moses by the command of God smote a rock and caused them to drink of a fountain thus opened for them. This rock is a suggestive type of Christ. It was here also that they encountered and defeated the Amalekites, a tribe of Edomites, who still kept up the enmity of Esau their father against Jacob. Here also Jethro, Moses' father-in-law came to them bringing Moses wife and sons. Upon Jethro's advice the people were thoroughly organized. From Rephidim they came to Mount Sinai where they encamped for a whole year.
