Book of Jasher (Sefer haYashar) 17

~267~ At that time, God said to Moses, your days are drawing near to death, take your servant Yehoshua son of Nun and stand in the tent of meeting and judge him, and Moses did so. And God saw a pillar of cloud in the tent, and the pillar of cloud stood at the entrance of the tent. And God commanded Joshua son of Nun and said to him, be strong and courageous because you will bring the children of Israel to the land that I swore to them and I will be with you. And Moses said to Joshua, be strong and courageous because you will inherit the land to the children of Israel and the Lord will be with you and will not let you down or leave you. Do not be afraid and do not suffer. And Moses called all Israel and said to them, You have seen all the good that the Lord your God did for you in the wilderness. And now keep all the words of this Torah and walk in the way of the Lord your God, do not deviate from the way that the Lord has commanded you to the right and to the left. And Moses taught the children of Israel laws and judgments and teachings to do in the land, when God commanded him. And he taught them the way of God and His teachings, which are written on the book of God's law that He gave to the children of Israel by the hand of Moses. And Moses was able to command the children of Israel, and God said to him to say. Go up to the mountain of the Hebrews and die there and gather to your people, when your brother Aaron was gathered. And Moses went up when God commanded him and died there in the land of Moab according to God, in the fortieth year of the children of Israel leaving the land of Egypt. And the children of Israel wept for Moshe in the plains of Moab thirty days, and the days of Moshe's mourning ended.
