Gemara 22:7b

(The Rabbis forced him to make doors and a lock for the city) And Rabban Shimon ben Gamliel says that not all towns are worthy of a wall, but a city that is close to the book is worthy of a wall, and one that is not close to the book is not worthy of a wall. And the Rabbis summoned Damkro and I gathered in a miniya Rabbi Elazar from Rabbi Yochanan when they taxed according to the number of people they taxed or according to the value of the wealth they taxed. He said to him: According to the wealth they taxed, and Elazar my son fixed nails in it. Here, I said in a miniya Rabbi Elazar from Rabbi Yochanan when they taxed according to the proximity of houses, they taxed or according to the value of the wealth they taxed, he said to him : According to the proximity of houses, they taxed and Elazar my son fixed nails in it.


How does the Rabbi understand the "praise of wealth" – benefit? Relative? Why did they [the recruit] come?
