OU TORAH Eikev By Rav Moshe Twersky, HY"D

( והיה עקב… (ז:יב Chazal call the time-period preceding yemos ha’Mashiach, Ikvesah d’Meshicha, the footheels of Mashiach. The heel of the foot has very little sensation relative to the rest of the body. The implication, then, of the term Ikvesah d’Meshicha, is that the people living in this time-period suffer with an acute lack of ability to feel. (From Reb Ari Deifik)
