Chazal tell us Avraham's actions towards the Melachim were zechusim that brought benefits in the Midbar, and that will bring benefits in the times of Mashiach. Why was the story with the Melachim a greater source of zechusin than all his earlier actions. Why is Hachnasas Orchim such a tremendous Mitzvah? Was Avraham the tallest person who ever lived?

Have a wonderful Shabbos
