Midrash su Salmi 59:7

Raba expounded again: "What is the meaning of the passage (Ps. 62, 4) How long will ye set upon a man? That ye may slay him, all of you, as a leaning wall, a tottering fence? Infer from this that they used to place a wealthy man under a tottering wall and pushed the wall over him, and robbed him of his money." Raba expounded again: "What is the meaning of the passage (Job 24, 16) In the dark they dig through houses, they shut themselves up; they know not the light. Infer from this that when they saw a wealthy man they used to deposit balsam with him, which usually the depositories placed in their treasure box, and in the night they smelled balsam and robbed him, as it is said (Ps. 59, 15) And they return evening, they howl like a dog; they then break in the place and steal the money, as the passage says (Job 24, 7) And have no covering, etc.; and again (Ib. ib) They drive away the ass, etc. (Ib. 21, 32) For he is born to the grave, etc., R. Jose lectured the same in Sepphorias. And the night after that lecture, three hundred burglaries were committed through the smell of balsam; the town men annyoed him, saying: "You have shown a way to the thieves." And he answered them: "How could I know that all [who will come to listen to me] are thieves?" It was said when R. Jose died, blood gushed from the spouts of the roofs of Sepphorias. The following was enacted in Sodom. He who possessed one ox had to pasture all the cattle of the city one day, but he who possessed none at all had to pasture them two days. There was an orphan, the son of a widow, to whom they gave their oxen to pasture, and he killed them, saying, (Ib. b) "Who has one ox shall take one skin, and he who has none at all shall take two skins." And to the question, "What is this?" he said to them: "The final trial must be as at the beginning of it. You enacted that he who has one ox shall pasture them one day, and he who has none at all shall pasture them two days. The same is the case with the skins." He who passed the river on a boat had to pay one zuz. And he who passed the river on foot had to pay two. If one had a row of bricks, every one of them came and took one, saying, I am not causing you any damage by taking one. The same they used to do when one scattered garlic or onions to dry.

All the household of Pharaoh's palace were (helping) to educate (Moses), as it is said, "And it came to pass in those days, when Moses was grown up, that he went out unto his brethren" (Ex. 2:11). Moses went into the camp of Israel, and saw one of the taskmasters of Pharaoh smiting one of the sons of Kohath, the Levites, for they were his brethren, as it is said, "And he saw an Egyptian smiting an Hebrew, one of his brethren" (ibid.). He began to rebuke him with the sword of his lips, and he slew him, and buried him in the midst of the camp, as it is said, "And he smote the Egyptian, and hid him in the sand" (Ex. 2:12). The word Chôl (sand) signifies (here) Israel only, as it is said, "Yet the number of children of Israel shall be as the sand of the sea" (Hos. 1:10).
