3:2-4 The Ark of the Covenant was Israel’s most sacred treasure. It was a symbol of God’s presence and power. The Ark was a gold rectangular box with two cherubim (angels) facing each other on the lid. Inside the Ark were the tablets of the Ten Commandments Moses received from God, a jar of manna (the bread God miraculously sent from heaven during the wilderness wanderings), and Aaron’s rod (the symbol of the high priest’s authority). According to God’s law, only the Levites could carry the Ark. The Ark was constructed at the same time as the Tabernacle (Exodus 37:1-9) and placed in the sanctuary’s most sacred room.
3:5 Before entering the Promised Land, the Israelites were to perform a purification ceremony. This was often done before making a sacrifice or, as in this case, before witnessing a great act of God. God’s law stated that a person could become unclean for many reasons—eating certain foods (Leviticus 11), giving birth (Leviticus 12), dealing with disease (Leviticus 13–14), touching a dead person (Numbers 19:11-22). God used these various outward signs of uncleanness to illustrate a person’s inward uncleanness that comes as a result of sin. The purification ceremony pictured the importance of approaching God with a pure heart. Like the Israelites, we need God’s forgiveness before we approach him.
3:9 Just before crossing over into the Promised Land, Joshua gathered the people to hear the words of the Lord. Their excitement was high. No doubt they wanted to rush on, but Joshua made them stop and listen. We live in a fast-paced age where everyone rushes just to keep up. It is easy to get caught up in our tasks, becoming too busy for what God says is most important—listening to his words. Before making your schedule, take time to focus on what God wants from all your activities. Knowing what God has said before you rush into your day can help you avoid foolish mistakes.
3:10 Why would God help the Israelites drive out these nations from their native land? God had punished Israel first for its disobedience. He then turned to the rest of the nations. Genesis 15:16 implies that the people of Canaan were wicked and deserved to be punished for their terrible sins. Israel was to be a vehicle for this punishment. More important was the fact that Israel, as a holy nation, could not live among such evil and idolatrous people. To do so would be to invite sin into their lives. The only way to prevent Israel from being infected by evil religions was to drive out those who practiced them. Israel, however, failed to drive everyone out as God had told them to do. It wasn’t long before Israel—the nation God chose to be his holy people—began following the evil practices of the Canaanites.
3:11 As the Israelites prepared to enter the land and divide up the territory, Joshua reminded them that God is Lord of the whole earth, not just of one part of it. Understanding this truth delivers us from thinking of our church, our nation, our family, or ourselves as the central figures on God’s stage. We are not central; God is. Although we are infinitely valuable in God’s sight, we must realize that he is weaving a grand design much larger than our personal interests and limited perspectives. God doesn’t exist to grant us personal success in all we do. We exist to serve him and fulfill his desires.
3:13, 14 The Israelites were eager to enter the Promised Land, conquer nations, and live peacefully. But first they had to cross the flood-level waters of the Jordan River. God gave them specific instructions: In order to cross, the priests had to step into the water. What if these priests had been afraid to take that first step? Often God provides no solution to our problems until we trust him and move ahead with what we know we should do. What are the rivers, or obstacles, in your life? In obedience to God, take that first step.
3:13-17 God had parted the waters of the Red Sea to let the people out of Egypt (Exodus 14), and here he parted the Jordan River to let them enter Canaan. These miracles showed Israel that God keeps his promises. God’s presence among his people and his faithfulness to them made the entire journey from Egypt to the Promised Land possible. He was with them at the end of their wanderings just as he was with them in the beginning.
3:15, 16 The Israelites crossed the Jordan River in the spring, when it was overflowing its banks. God chose the time when the river was at its highest to demonstrate his power—parting the waters so that the entire nation could cross on dry ground. Some say that God used a natural occurrence (such as a landslide) to stop the waters of the Jordan; others say he did it by a direct act. In either case, God showed his great power by working a miracle of timing and location to allow his people to cross the river on dry ground. This testimony of God’s supernatural power served to build the Israelites’ hope in God and to give them a great reputation with their enemies, who greatly outnumbered them.
