Joshua son of Nun and Caleb son of Jephunneh, who were among those who scouted out the land, tore their clothes and said to the entire Israelite community, “The land we passed through and explored is an extremely good land. If the Lord is pleased with us, he will bring us into this land, a land flowing with milk and honey, and give it to us. Only don’t rebel against the Lord, and don’t be afraid of the people of the land, for we will devour them. Their protection has been removed from them, and the Lord is with us. Don’t be afraid of them!” While the whole community threatened to stone them, the glory of the Lord appeared to all the Israelites at the tent of meeting.
Numbers 14:6-10

Tell them: As I live—this is the Lord’s declaration—I will do to you exactly as I heard you say. Your corpses will fall in this wilderness—all of you who were registered in the census, the entire number of you twenty years old or more—because you have complained about me. I swear that none of you will enter the land I promised to settle you in, except Caleb son of Jephunneh and Joshua son of Nun.
Numbers 14:28-30

After the death of Moses the Lord’s servant, the Lord spoke to Joshua son of Nun, Moses’s assistant: “Moses my servant is dead. Now you and all the people prepare to cross over the Jordan to the land I am giving the Israelites. I have given you every place where the sole of your foot treads, just as I promised Moses. Your territory will be from the wilderness and Lebanon to the great river, the Euphrates River—all the land of the Hittites—and west to the Mediterranean Sea. No one will be able to stand against you as long as you live. I will be with you, just as I was with Moses. I will not leave you or abandon you.
Joshua 1:1-5

I have given you every place where the sole of your foot treads
No one will be able to stand against you as long as you live
I will be with you.
I will not leave you or abandon you.

“Be strong and courageous, for you will distribute the land I swore to their ancestors to give them as an inheritance. Above all, be strong and very courageous to observe carefully the whole instruction my servant Moses commanded you. Do not turn from it to the right or the left, so that you will have success wherever you go. This book of instruction must not depart from your mouth; you are to meditate on it day and night so that you may carefully observe everything written in it. For then you will prosper and succeed in whatever you do. Haven’t I commanded you: be strong and courageous? Do not be afraid or discouraged, for the Lord your God is with you wherever you go.”
Joshua 1:6-9

Anyone who rebels against your order and does not obey your words in all that you command him, will be put to death. Above all, be strong and courageous!”
Joshua 1:18

Before the men fell asleep, she went up on the roof and said to them, “I know that the Lord has given you this land and that the terror of you has fallen on us, and everyone who lives in the land is panicking because of you. For we have heard how the Lord dried up the water of the Red Sea before you when you came out of Egypt, and what you did to Sihon and Og, the two Amorite kings you completely destroyed across the Jordan. When we heard this, we lost heart, and everyone’s courage failed because of you, for the Lord your God is God in heaven above and on earth below.
Joshua 2:8-11
