"...the people rushed into the city, every man straight in front of him, and they captured the city. They exterminated everything in the city with the sword: man and woman, young and old, ox and sheep and ass. But Joshua bade the two men who had spied out the land, 'Go into the harlot's house and bring out the woman and all that belong to her, as you swore to her'. So the young spies went in and brought out Rahab, her father and her mother, her brothers and all that belonged to her- they brought out her whole family and left them outside the camp of Isreal.
They burned down the city and everything in it. But the silver and gold and the objects of copper and iron were deposited in the treasury of teh House of ADONAI. Only Rahab the harlot and her father's family were spared by Joshua, along with all that belonged to her, and she dwelt among the Israelites- as is still the case. For she had hidden the messengers that Joshua sent to spy out Jericho." - JOSHUA 6:20-25

"When Israel had killed all the inhabitants of Ai who had pursued them into the open wilderness, and all of them, to the last man, had fallen by the sword, all the Israelies turned back to Ai and put it to the sword.
The total of those who fell that day, men and women, the ENTIRE POPULATION OF AI, came to twelve thousand.
Joshua did not draw back the hand with which he held out his javaelin until all the inhabitants of Ai had been exterminated. However the Israelites took the cattle and the spoil of the city as their booty, in accordance with the instructions that ADONAI had given to Joshua.
Then Joshua burned down Ai, and turned it into a mound of ruins for all time, a desolation to this day. And the king of Ai was impaled on a stake until the evening. At sunset, Joshua had the corpse taken down from teh stake and it was left lying at the entrance of the city gate. They raised a great heap of stones over it, which is there to this day." - JOSHUA 8:24-29

"Joshua then turned back and captured Hazor and put her king to the sword. -Hazor was formerly the head of all those kingdowms.- They proscribed and put to the sword every person in it. not a soul survived, and Hazor itself was burned down."
- Joshua 11:10-11

Hashem commanded Joshua to kill all the inhabitants of the lands that the Isrealites were to take over. The above passages are examples of Joshua's carrying out of this commandment. As you will (hopefully) read further, you will see that the Israelites continue to allow those who do not believe in Hashem and follow his commandments to live amongst them (the Isrealites), which results in the Isrealites falling for pagan gods and idol worship. This allowance of Gentiles amongst the Isrealite nation results in the eventual captivity at the hands of Babylon. History repeats itself, this time with InI Rastafari Idren.
