Joshua 1:3-6
"Every place that the sole of your foot shall tread upon, that have I given unto you, as I said to Moses. From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast. There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee. Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land which I swore unto their fathers to give them."
This is inauguration of Joshua, and he must speak the word of the Lord to the people before they begin their next conquest. In chapter two Joshua sends a couple spies off to live with Rahab, an alleged prostitute, and gather information from the walled-off Jericho. Thereafter, Joshua collects his infantry, speaks the word of the Lord unto them, cleanses them, and passes them over. It's only been 4 & 1/2 books into Joshua and he's already gained so much respect that "On that day the Lord magnified Joshua in the sight of all Israel; and they feared him, as they feared Moses, all the days of his life."(Joshua 4: 14) God is going about his usual routine. He gets the ear of one human and asks/commands them to preach His words, which are passionate yet quite violent and ethnocentric. "And Joshua said unto the children of Israel, 'Come hither, and hear the words of the Lord your God.' And Joshua said, 'Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.'"(Joshua 3:9-10) These words contain promises and initiate actions which are attempts to 'send a message' to His non-followers (non-knowers) using power and force over diplomacy. God has many rules and obligations which all seems to have and endpoint along the same merciless lines.
Now this is actually a story I know and taught; Joshua and the walls of Jericho. It's now time for Joshua and his/God's followers begin their quest to claim the next prized real estate. Joshua and his army circle the wall once each day for six days then circle it seven times on the seventh day. The walls come tumbling down and it's open season. The warriors had pillage the city and kill each blasphemer (including those who know not of blasphemy). No inhabitant nor house must be saved, but one expensive tithe is Jericho's exception. I didn't know that all the treasure was to be collected and put aside for the Lord.
But wait, there's one survivor, that being Rahab. Sure, she gave Joshua's chosen men hospitality, but what exactly was those men's purpose? They spied for what benefit? They must have been in it for the booty (pun intended?).
