Joseph's coffin in the possession of Moses, the march of the Israelites could begin. The Egyptians put no manner of obstacle in their way. Pharaoh himself accompanied them, to make sure that they were actually leaving the land, and now he was so angry at his counselors for having advised against letting the Israelites depart that he slew them.

For several reasons God did not permit the Israelites to travel along the straight route to the promised land. He desired them to go to Sinai first and take the law upon themselves there, and, besides, the time divinely appointed for the occupation of the land by the Gentiles had not yet elapsed. Over and above all this, the long sojourn in the wilderness was fraught with profit for the Israelites, spiritually and materially. If they had reached Palestine directly after leaving Egypt, they would have devoted themselves entirely each to the cultivation of his allotted parcel of ground, and no time would have been left for the study of the Torah. In the wilderness they were relieved of the necessity of providing for their daily wants, and they would give all their efforts to acquiring the law. On the whole, it would not have been advantageous to process at once to the Holy Land and take possession thereof, for when the Canaanites heard that the Israelites were making for Palestine, they burnt the crops, felled the trees, destroyed the buildings, and choked the water springs, all in order to render the land uninhabitable. Hereupon God spake, and said: "I did not promise their fathers to give a devastated land unto their seed, but a land full of all good things. I will lead them about in the wilderness for forty years, and meanwhile the Canaanites will have time to repair the damage they have done." Moreover, the many miracles performed for the Israelites during the journey through the wilderness had made their terror to fall upon the other nations, and their hearts melted, and there remained no more spirit in any man. They did not venture to attack the Israelites, and the conquest of the land was all the easier.
