Ako'y walumpung taong gulang na ngayon; makikilala ko pa ba ang mabuti at ang masama? Malalasahan pa ba ng iyong lingkod ang aking kinakain at ang aking iniinom? Maririnig ko pa ba ang tinig ng mga mang-aawit na lalaki at babae? Kaya bakit pa magiging pabigat ang iyong lingkod sa aking panginoong hari?
Rashi
Between something good or bad? Between good food and bad food. Our Rabbis of blessed memory said, He overindulged in sexual relations causing old age to overtake him.7Shabbos 152a. Otherwise even an eighty year old man would not have deteriorated to that extent.
