Midrash sa Ezekiel 15:5: Bereshit Rabbah

“He commanded the one in charge of his house, saying: Fill the men's sacks with food, as much as they are able to carry, and place each man's silver at the opening of his sack” (Genesis 44:1).
“And place my goblet, the silver goblet, at the opening of the sack of the youngest, and the silver of his purchase of the grain. He did in accordance with the statement that Joseph had spoken” (Genesis 44:2).
“Morning broke, and the men were dispatched, they and their donkeys” (Genesis 44:3).
“He commanded the one in charge of his house…Morning broke...” Rabbi Levi said: There was an incident in the South¹²In the land of Judah. regarding a certain innkeeper, who would rise and don his garments at night and he would say to those who were there: ‘Arise and go on your way, as I will arrange a caravan to accompany you.’ They would go out, robbers would meet them and plunder them, and they would come and divide [the spoils] with him. One time, Rabbi Meir went and was received there. [The innkeeper] arose and donned his garments and he said to him: ‘Arise and go on your way, as I will arrange a caravan to accompany you.’ He said to him: ‘I have a brother, and I am sitting and waiting for him.’ He said to him: ‘Where is he?’ He said to him: ‘In the synagogue.’ He said to him: ‘What is his name? I will go and call him.’ He said to him: ‘Ki tov.’ That entire night, that innkeeper shouted at the entrance of the synagogue: ‘Ki tov, Ki tov,’ but no one answered him. In the morning, Rabbi Meir rose and bridled his donkey in order to depart. The innkeeper said to him: ‘Where is that brother of whom you spoke?’ He said to him: ‘He has arrived: “God saw the light, that it was good [ki tov]”’ (Genesis 1:4).

“Behold, silver that we found in the opening of our sacks, we returned to you from the land of Canaan; how would we steal from the house of your lord silver or gold?” (Genesis 44:8).
“Behold, silver…” – Rabbi Yishmael taught: This is one of the ten a fortiori inferences that are written in the Torah: “Behold, silver…we returned to you,” all the more so, “how would we steal?” “Behold, the children of Israel did not heed me” (Exodus 6:12), and all the more so, “how will Pharaoh heed me?” (Exodus 6:12). “The Lord said to Moses: And if her father spit in her face, would she not be ashamed seven days?” (Numbers 12:14), all the more so, for [a rebuke from] the Divine Presence, [she should be ashamed] fourteen days. “Behold, while I am still alive with you today, you have been defiant” (Deuteronomy 31:27), all the more so, “so too, after my death” (Deuteronomy 31:27). “For you ran against those on foot and they exhausted you” (Jeremiah 12:5), all the more so, “how will you compete with horses?” (Jeremiah 12:5). “In a land of peace where you are secure” (Jeremiah 12:5), [you are overcome], all the more so, “how will you fare in the thickets of the Jordan?” (Jeremiah 12:5). “Behold, here in Judah we are afraid” (I Samuel 23:3), “all the more so, if we go to Ke'ila” (I Samuel 23:3). “Behold, restitution will be made to the righteous on earth, all the more so the wicked and the sinner” (Proverbs 11:31). “The king said to Queen Esther: In Shushan the citadel [the Jews have killed and eliminated five hundred men]” (Esther 9:12), all the more so, “what must they have done in the rest of the king’s provinces?” (Esther 9:12). “Behold, when it was whole it could not be used for labor, all the more so when fire has consumed it and it is charred” (Ezekiel 15:5).
