This is a question my son asked I couldn't answer.
- Yitzhok was extremely wealthy.
- When sending out Eliezer to bring Rivka, Abraham wrote him an inheritance bill for Yitzhok.
- When Yaakov "ran away" he took some money that was stolen by Elipaz (acc. to Midrash)
- When he finally got to Lavan, Yaacov could easily send messengers back to his father to provide him with all the money he needed to buy Rachel and Leah and whatever he needed to live happily and learn Torah worry-free. However, he never contacted his father (not documented anyway).
- The Halocho says we always should minimize our tests (Nisayon) and get out of problematic situations (staying with Lavan, worries with marriages) as fast as possible, and pay all the money needed.
So why didn't he do it?
