Why was Ya'akov only concerned that Lavan would steal his daughters (Ya'akov's wives), and not anything else?
Seforno: As a matter of fact, he was worried that he would hold back his daughters, as an excuse to steal his (Ya'akov's) sons and his money, 1 with the help of his townspeople.
Tosfos ha'Shalem (3, citing R. Efrayim): Money can be replaced, but nothing can be in place of your daughters.
As Lavan himself intimated (See Pasuk 43).
How does Ya'akov's answer tally with Lavan's accusation that he stole his gods?
Rashi and Rashbam: It doesn't! It answers his first accusation - that he led away his daughters like captives. Ya'akov's answer to his accusation concerning his gods lies in the following Pasuk. 1
In keeping with the Mishnah in Pirkei Avos (5:7), that a wise person answers the questions that are put to him in the order that they are asked.
