Friends, you know how a baby when he nurses for 15 min then goes to sleep for a few hours from all his hard work. try to imagine waking him up and showing him all the food he going to eat all the rest of his life. A river of milk, a lake of orange juice, an ocean of water. a costco stuffed with meat, a home depot filled with grains, breads and cereals. a wallmart stuffed with f ruits and vegetables and a mountain of potatoes. and we tell this baby this all the food you have to eat. he is going to tell you. wow, i cant do it, it is too much work. so this baby was born he was 7.7 when he will die he will be 197.7 so all that food for 190 pounds? why go through the motions the answer is that every time we make a bracha, that lasts for ever. When you light the menorah, that light from that Mitzva lasts forever. The same thing with Torah, you really teach a person Torah he will remember it forever. Yaakov taught Yosef about eglah arufah 23 years earlier, but that is where Yosef was holding bec it stayed with him forever.
Good Shabbos
