How did Lavan respond to Yakov's explanation?
Rashi: He pointed out that, since Yakov was unable to pay anything, he was under no obligation 1 to take him in. 2 Only, since he was family, he would kindly invite him for one month - not free of charge, but on condition that he tend to his sheep. 3
Rashbam: He told him that since he was his own flesh and blood, coming to him was a wise choice.
Seforno: He told him that, even though he did not need him for Parnasah, nevertheless, since he was his own flesh and blood, it was only correct that he stay with him.
Riva: We learn from "Ach", which is an exclusion.
Tosfos ha'Shalem (3, citing Sefer ha'Gan): It is proper that I distance you, like you were distanced from your family for swindling your brother twice. However, I will not do so.
Why did Yakov enter Lavan's house without insisting that Lavan remove the idolatry?
Moshav Zekenim: He wanted to see whether Rachel and Leah 1 served idolatry. After a month, he separated from Lavan.
Why did Lavan say "you are my bone and flesh?"
Kol Eliyahu, Divrei Eliyahu: A baby's bones are due to his father; his flesh is due to his mother. You are my bone and flesh, for both your father (our grandfathers were brothers) and mother are related to me. 3
Refer to 29:14:153:5.
Tosfos ha'Shalem (4, from Bereishis Rabah): Lavan recognized that Yakov is Tam (pure, simple). He could not swindle a stranger like he could swindle Yakov.
Yakov had nothing now! Perhaps he intended for what Yakov will acquire or inherit. (PF)
Lavan said "Ach Atzmi u'Vesari Atah." What does Ach exclude?
Ohr ha'Chayim #1: His nature is different
Why did Lavan house Yakov for a month?
Ohr ha'Chayim #1: He was waiting to see if Yakov's property will come. When it did not, he despaired, and chose how to deal with him.
Ohr ha'Chayim #2: He was planning that Yakov will work for him. He tested him, and saw that he was succeeding.
