Note: Here is a more extensive proposal for the link between Deuteronomy and Joshua. The centre is the handover from Moses to Joshua.
A. 1 And Moses went up from the plains of Moab unto the mountain of Nebo, to the top of Pisgah, that is over against Jericho. And the LORD shewed him all the land of Gilead, unto Dan, 2 And all Naphtali, and the land of Ephraim, and Manasseh, and all the land of Judah, unto the utmost sea, 3 And the south, and the plain of the valley of Jericho, the city of palm trees, unto Zoar.
B. 4 And the LORD said unto him, This is the land which I sware unto Abraham, unto Isaac, and unto Jacob, saying, I will give it unto thy seed: I have caused thee to see it with thine eyes, but thou shalt not go over thither.
C. 5 So Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD. 6 And he buried him in a valley in the land of Moab, over against Bethpeor: but no man knoweth of his sepulchre unto this day.
D. 7 And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated.
E. 8 And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended.
F. 9 And Joshua the son of Nun was full of the spirit of wisdom; for Moses had laid his hands upon him:
E’. and the children of Israel hearkened unto him, and did as the LORD commanded Moses.
D’. 10 And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face, 11 In all the signs and the wonders, which the LORD sent him to do in the land of Egypt to Pharaoh, and to all his servants, and to all his land, 12 And in all that mighty hand, and in all the great terror which Moses shewed in the sight of all Israel.
C’. 1 Now after the death of Moses the servant of the LORD
B’. it came to pass, that the LORD spake unto Joshua the son of Nun, Moses’ minister, saying, 2 Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, even to the children of Israel.
A’. 3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses. 4 From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast.
