מדרש על בראשית 37:25

And Jacob sat in the land (Gen. 37:1). Whenever Scripture uses the expression and he sat (also translated “and he dwelt”), it connotes misfortune: And Israel sat in the land of Egypt, in the land of Goshen, … and the time drew near that Israel must die (Gen. 47:29); And the people sat down to eat and drink, and rose up to make merry (Exod. 32:37); And there fell of the people on that day three thousand men (Exod. 38:28); And they sat down to eat bread; and they lifted up their eyes and looked, and, behold, a caravan of Ishmaelites (Gen. 37:25); And Judah and Israel sat safely (I Kings 5:5); And the Lord raised up an adversary against Solomon (ibid. 11:14); And Israel sat among the cedars, etc., and the people began to commit harlotry (Num. 25:1). You may explain every other use of “and he sat” with this negative implication. In this instance And Jacob sat is followed by and Joseph brought evil report of them unto his father (Gen. 37:2).

And they sat down to eat bread (ibid., v. 25). R. Judah the son of Shalum said: This is a notable instance of many sitting down together in unity, with a single thought in mind; to sell Joseph. Yet he fed the world for seven years, through two famines. If despite their sin he could feed the world and cause it to endure, how much more beneficial would have been the result if they had acted meritoriously. Similarly, observe what happened to the tribes in the chapter Shekalim, when they were permitted to atone for the incident of the golden calf. If the heinous sin they committed could lead to the performance of a worthy act, how much more so if they had acted meritoriously.

“The couriers went out urgently by the king’s command, and the order was issued in the Shushan citadel; the king and Haman sat to drink, and the city of Shushan was confounded” (Esther 3:15).
“The couriers went out urgently by the king’s command… the king and Haman sat to drink.” Rabbi Ḥanin said: Anyone who says that the All-Merciful is forbearing, his innards will be forborne. Rather, He withholds His anger, but [later] collects His due. He said to the tribes: ‘You sold your brother while eating and drinking. I will do the same to you;’²³Joseph’s brothers “sat down to eat a meal” (Genesis 37:25) when they came up with the idea of selling Joseph into slavery. that is what is written: “And the king and Haman sat to drink.”
There was a certain man of Israel who went to the marketplace to purchase a litra of meat or a bunch of greens; a Persian choked him and said to him: ‘Tomorrow I will kill you and spend your money’; that is what is written: “And the city of Shushan was confounded.”
Rabbi Yissakhar of Kefar Mandi said: See how long it takes for the resolution [of the statement] of one who forgave, saying: “It was not you who sent me here, but rather God…” (Genesis 45:8).²⁴Joseph to his brothers. The punishment for the sale of Joseph was in effect until the days of Mordekhai; for one who does not forgive, all the more so.
