Very nice.
The Ksav Sofer in Parashas Shmini explains the expression מתי ימותו זקנים הללו ואני ואתה ננהיג הצבור when will these elders die and we will be leaders. It sounds very strange that they hoped that the elders will die and they will become leaders. They took a lesson from Moshe Rabbenu that his children did not behave properly because he did not have time to spend with them to raise them as he was busy with leadership. They said if they will die, we become leaders and we won’t be able to bring up our children properly. Therefore, they decided not to get married to have children. This was a strange fire figuratively in their mind as Chezkiya did not want to get married to have Menasheh.
