Deuteronomy 31:1-8
“When Moses had finished giving these instructions to all the people of Israel, he said, ‘I am now 120 years old, and I am no longer able to lead you. The Lord has told me, ‘You will not cross the Jordan River.’ But the Lord your God himself will cross over ahead of you. He will destroy the nations living there, and you will take possession of their land. Joshua will lead you across the river, just as the Lord promised.’
‘The Lord will destroy the nations living in the land, just as he destroyed Sihon and Og, the kings of the Amorites. The Lord will hand over to you the people who live there, and you must deal with them as I have commanded you. So be strong and courageous! Do not be afraid and do not panic before them. For the Lord your God will personally go ahead of you. He will neither fail you nor abandon you.’
Then Moses called for Joshua, and as all Israel watched, he said to him, ‘Be strong and courageous! For you will lead these people into the land that the Lord swore to their ancestors he would give them. You are the one who will divide it among them as their grants of land. Do not be afraid or discouraged, for the Lord will personally go ahead of you. He will be with you; he will neither fail you nor abandon you.'”
Joshua 1:1-8
“After the death of Moses the Lord’s servant, the Lord spoke to Joshua son of Nun, Moses’ assistant. He said, ‘Moses my servant is dead. Therefore, the time has come for you to lead these people, the Israelites, across the Jordan River into the land I am giving them. I promise you what I promised Moses: ‘Wherever you set foot, you will be on land I have given you— from the Negev wilderness in the south to the Lebanon mountains in the north, from the Euphrates River in the east to the Mediterranean Sea in the west, including all the land of the Hittites.’ No one will be able to stand against you as long as you live. For I will be with you as I was with Moses. I will not fail you or abandon you.’
‘Be strong and courageous, for you are the one who will lead these people to possess all the land I swore to their ancestors I would give them. Be strong and very courageous. Be careful to obey all the instructions Moses gave you. Do not deviate from them, turning either to the right or to the left. Then you will be successful in everything you do. Study this Book of Instruction continually. Meditate on it day and night so you will be sure to obey everything written in it. Only then will you prosper and succeed in all you do.'”
Joshua 3:5
“Then Joshua told the people, ‘Purify yourselves, for tomorrow the Lord will do great wonders among you.'”
