Question: It is said in the book of the Prophets that after Joshua entered the city of Ai with his army, all the citizens of the city were destroyed, as well as those soldiers who were lured out of the city. In total, 12,000 people were killed: husbands and wives.
Why is it said: “husbands and wives”? What does this mean?
Answer: We are talking about two lines. There are cities where you can destroy only the male population, and leave the female population, or destroy women and leave only virgins, and so on.
This means that in each case you can attach different quantities of egoism aimed at acting for the sake of bestowal to yourself and absorb them into yourself to use them correctly.
In this case, it is necessary to destroy both lines because the nation has only entered the land of Israel. It has not conquered anything yet; it has not subjugated anything to the quality of bestowal; it does not yet have a common screen. Therefore, for the time being, they must destroy the desire called the city of Ai and not use it at all.
