Prophets, Joshua, 8:1; 8:17-8:19: And the Lord said to Joshua, Fear not, and be not dismayed; take all the people of war with you and arise, go up to Ai. See, I have given into your hand the king of Ai, and his people, and his city, and his land.
And there was not a man left in Ai or Beth-el, that did not go out after Israel; and they left the city open, and pursued Israel.
And the Lord said to Joshua, Stretch out the spear that is in your hand, toward Ai; for I will give it into your hand. And Joshua stretched out the spear that was in his hand, toward the city.
And the ambush arose quickly out of their place, and they ran as soon as he had stretched out his hand; and they entered into the city, and took it, and hastened and set the city on fire.
Question: Does it mean that as long as he holds the spear, people will have the strength to conquer the city?
Answer: No, this is not about people. The Torah addresses a single person and indicates how he should behave in such and such circumstances. It gives examples of how to overcome your egoism, how to conquer it. The Torah does not speak about anything else.
The seizure and destruction of the city mean the destruction of the egoistic desire in a person. Such cities and countries exist within every person. The entire universe is within him.
Question: Why does it say that one should raise his hand with a spear and hold it?
Answer: So that under no circumstances you would miss this particular action and this opportunity to conquer the egoistic property within yourself.
