Комментарий к Берешит 32:1

ויברך אתהם. Our sages have already told us not to belittle the value of a blessing pronounced by a layman, a person of low social standing. (Megillah 15) The reason why the Torah tells us of Lavan’s blessing to his daughters is to remind us that when a father blesses his sons he does so wholeheartedly, with his material and spiritual faculties. We know that Yitzchok blessed with all his soul from his own words (27,4) When the one bestowing the blessing himself reflects the image of G’d he had been created in, then such a blessing is likely to be correspondingly more effective.

Lavan … returned to his place. He returned to the lowly status that he endured before Yaakov arrived. This foreshadowed the ascendance and subsequent decline of all the nations that hosted and then expelled the Jewish people.

וישכם, the word has been explained elsewhere.

וינשק לבניו, ”he kissed his grandchildren.” His daughters children.
