Shalom Chaim,
Is there any explanation in the Bible or by commentary by the great Jewish Sages in why many people mentioned in the Five Books of Moses lived much longer lives than the vast majority of people did in the Common Era? What really stands out is that in the modern era with all of the advances in medicine and science, the average person doesn't live remotely close as long compared to the people I'm going to list. According to what I saw in various commentary, the following are some of the ages that people lived in the days of the Five Books of Moses:
Isaac, 180 years; Abraham, 175; Jacob, 147; Ishmael, 137; Sarah, 127; Moses, 120; Joseph and Joshua, 110 years.
Thanks as always, eb22.
