What does Genesis 30:31 mean?
Laban is ready to hear Jacob's offer. He knows he has grown rich because of the Lord's blessing on his son-in-law. He doesn't want Jacob to return to his own people, as Jacob has asked to do. In that era, since Jacob was a servant of Laban, his entire family would have been considered part of Laban's property, as well. In order to leave, without being accused of theft, he needs Laban to agree with their departure.Instead of insisting on leaving right away, Jacob has come up with a plan to gain some wealth for himself. He is aware that Laban is a tough—and deceptive (Genesis 29:18–30)—negotiator. He is also counting on the fact that the Lord will continue to bless him abundantly.
Laban asks again: What do you want from me? Jacob surprises him with a tricky answer of his own: Don't give me anything right now. Instead, Jacob will ask for a specific cut of the future profits in the following verses. Laban, predictably, will respond by trying to cheat Jacob.
