Wed Sotah 37

Binyamin jumped in first and Yehudah was throwing stones.

Tosfos quotes Michltin that gives a parable. This is similar to a king that gives instructions to his younger son to wake him at dawn. He then instructed his alder son to wake him three hours in the day. When the younger son came to wake his father, the older son protested, until the commotion woke the father. The father said since you both did this for my sake, I will reward you both.

(I assume that there was a basic argument between Binyamin and Yehudah when to jump in, and Yehudah was waiting for the more apt time and thus protested Binyamin for jumping in early.)

Tues Sotah 36

When Yosef returned to the house, he saw his father's image in the window.

Toafos quotes R' Moshe the Darshen: this Drasha was learned from the following implication. The Torah writes that there was no man from the household there. This implies that there was someone not from the household, which would be Yaakov.

However, Tosfos asks: where do we see that he was in the window?

Tosfos answers: perhaps because the Torah says there was no one etc. in the house, implies there was someone just out of the house.
