Joshua was a very faithful servant to God and to Moses, and was very obedient ,Victory of faith was rewarded by leading into Canaan.Joshua and Caleb were the only two of the old generation were permitted into the new promised land. he was Moses’s personal aide and commander and Moses lead them up to Canaan and Joshua was commanded to lead into the land of Canaan. First 5 Books are the history of Moses written by Moses the journey from Egypt to up to the land of Canaan. From Joshua to Esther it is the history of Israel in the land of Canaan. Numbers it says he was full of The Holy Spirit. He was the spiritual disciple of Moses and also accompanied Moses up to the Mountain to receive Torah. He continued to be military commander in taking over Canaan and the administrator of allotting the land to the children of Israel and God was leading him every inch of the way.The Lords charge to Joshua is repeated from Deuteronomy 31:6,7,23.
The crossing of the Jordan river and another miracle waters of Jordan divided, like the crossing of the Red Sea.carrying the Ark of the covenant- which symbolized the presence of God, people were commanded to be reverence and to follow it and be a distance away from it and to be clean. this is important because the other generation was in the same place 40 yrs ago. after they crossed they did a memorial in Gilgal remembering the power of God holding the waters still while they crossed, and the faithfulness of God to bringing them in and keeping the promise. Each memorial was made up of twelve stones.
chapter 2 mentions about the spy Joshua sent before he went o war to take over Jericho and stayed in a harlot named Rehab. so when they conquered Jericho she and her whole family were saved.
Gilgal is where God rolled away the reproach of Egypt. the era of captivity came to an end. This is also compared with Golgotha where mankind`s captivity of sin ended. The circumcision of the new generation was done to seal the covenant of God. , as per Abrahamic covenant to ready the people to lead into the possession of the land. Since they have to be faithful and completely dependent of God. They kept the Passover on the 14th day of the month. They ate old corn after the day after Passover and there after the giving of the Manna ceased .and were blessed with the food of the land.
chapter 6, The division of the land. Chapter describes the kings defeated by Moses and the Joshua, in chapter 13-19, The direction of the land in Chapter 20-24.
it also covers the 6 cities of refuge 3 on the west and 3 on the east that is when the children of Israel did something wrong unknowingly they were protected there. Just like in New Testament Christ is our refuge.
Also the command concerning the levitical cities.
The three things God gave Israel are all the land ,Rest after the journey and all the enemies into their hand. The principles are to obey him and to accomplish all that He asks,to the last details which pleases God and he rewards those who do His will.Similarly Jesus has given us a way to win Satan, and all we have to do is choose to acquire it out of our own will and Belief. Believe that Jesus is the son of God and He died on the cross to redeem us from our sins.and arose on the 3rd day victoriously that we may find everlasting life.
Jesus is our Salvation.
