13:17-20 There were two ways from Egypt to Canaan. One was only a few days' journey; the other was much further about, through the wilderness, and that was the way in which God chose to lead his people Israel. The Egyptians were to be drowned in the Red sea; the Israelites were to be humbled and proved in the wilderness. God's way is the right way, though it seems about. If we think he leads not his people the nearest way, yet we may be sure he leads them the best way, and so it will appear when we come to our journey's end. The Philistines were powerful enemies; it was needful that the Israelites should be prepared for the wars of Canaan, by passing through the difficulties of the wilderness. Thus God proportions his people's trials to their strength, 1Co 10:13. They went up in good order. They went up in five in a rank, some; in five bands, so others, which it seems rather to their faith and hope, that God would bring them to Canaan, in expectation of which they carried these bones with them while in the desert.

19. Moses took the bones of Joseph with him—in fulfilment of the oath he exacted from his brethren (Ge 50:25, 26). The remains of the other patriarchs (not noticed from their obscurity) were also carried out of Egypt (Ac 7:15, 16); and there would be no difficulty as to the means of conveyance—a few camels bearing these precious relics would give a true picture of Oriental customs, such as is still to be seen in the immense pilgrimages to Mecca.
