Class One. Two levels are extracted from this Possuk. The first is the Possuk by itself, that says that people who learn Torah are Hashem’s children and they have peace. The second is how this Possuk is understood by the חז”ל אל תקרי בניך אלא בוניך that their Torah is מברר the world. The peace this second group brings to the world and to themselves is far greater than the first idea of peace. This is connected to Ya’akov apologizing for delaying meeting עשיו because he needed to first finish the בירור of לבן before he could meet עשיו. This is because the order of בירור by יעקב is from the top down.
Class Two. The question is what can we learn from how יעקב did בירור since our order of בירור is from the bottom up. The Rebbe says a number of answers: 1) our בירור is based on his though he did it in the opposite order. 2) We also have somewhat of an idea of בירור מלמעלה למטה. In Chassidus there is בירור in that order even by us even now. It affects the learning of נגלה דתורה also.
