When the people crossed the River Jordan with the Ark of the Covenant, the River Jordan stopped flowing so they could cross on dry land. This wondrous event manifested to the people already in Canaan the power of God. Joshua 3:14-17 The people struck their tents to cross the Jordan, with the priests carrying the ark of the covenant ahead of them. No sooner had these priestly bearers of the ark waded into the waters at the edge of the Jordan, which overflows all its banks during the entire season of the harvest, than the waters flowing from upstream halted, backing up in a solid mass for a very great distance indeed, from Adam, a city in the direction of Zarethan; while those flowing downstream toward the Salt Sea of the Aragah disappeared entirely. Thus the people crossed over opposite Jericho. While all Israel crossed over on dry ground, the priests carrying the ark of the covenant of the LORD remained motionless on dry ground in the bed of the Jordan until the whole nation had completed the passage.
Joshua was the leader of the people now. The Book of Joshua described his time of leading the Israelites. There is just one reference to the Name of the LORD in the Book of Joshua.
The Ark of the Covenant was taken in procession around Jericho and on the seventh day, that settlement fell to the Hebrews. The LORD banned the Israelites from removing any artifacts from Jericho. One person violated the ban. The LORD’s favor was removed because of this disobedience. During the next battle at Ai (the next settlement that the Hebrews were going to overtake), they were defeated and had to retreat in humiliation. Joshua cried out to the LORD Joshua 7:9-13 “When the Canaanites and the other inhabitants of the land hear of it, they will close in around us and efface our name from the earth. What will you do for your great Name?”
The LORD replied to Joshua: “Stand up. Why are you lying prostrate? Israel has sinned: they have violated the covenant which I enjoined on them. They have stealthily taken goods subject to the ban, and have deceitfully put them in their baggage. If the Israelites cannot stand up to their enemies, but must turn their back to them, it is because they are under the ban. I will not remain with you unless you remove from among you whoever has incurred the ban. Rise, sanctify the people. Tell them to sanctify themselves before tomorrow, for the LORD, the God of Israel, says: You are under the ban, O Israel. You cannot stand up to your enemies until you remove from among you whoever has incurred the ban.“
