Midras Kejadian 34:30: Midrash Tanchuma, Sefer HaYashar (midrash), Shemot Rabbah & Pirkei DeRabbi Eliezer

A company of priests alludes to the sons of Jacob, who had been called a kingdom of priests. Why does Scripture say: They murder in the way to Shechem? Because they committed an immoral act. Upon their return, Jacob began to chastise Simeon and Levi, saying: Ye have troubled me, to make me odious (Gen. 34:30). The Holy One, blessed be He, said to him: Be not afraid, no one can harm you, as it is said: And a terror of God was upon the cities (ibid. 35:5).

and Potiphar said unto them: Name the value of that youth. And they said: We want for him ‎four hundred pieces of silver. And Potiphar said unto them: I am ready to pay you the amount ‎if you will bring unto me him that hath sold the youth unto you and inform me concerning his ‎affairs; peradventure he hath been stolen, for the youth is neither a slave nor the son of a ‎slave, for I see noble blood within him. And the Midianites went away and they brought the ‎Ishmaelites who had sold Joseph unto them, and the Ishmaelites said unto Potiphar: He is a ‎slave, and we have sold him unto these men. And when Potiphar heard their words he paid ‎the silver unto the Midianites and they went away and the Ishmaelites returned likewise to ‎their place. And Potiphar took Joseph and he brought him into his house and he served ‎Potiphar. And Joseph found grace in Potiphar’s eyes, and he trusted in him, and he made him ‎overseer in his house and all that he had Potiphar surrendered into his care. And the Lord was ‎with Joseph and he was a prosperous man and the Lord blessed the house of Potiphar for ‎Joseph’s sake, and he left all that he had in Joseph’s hand. And Joseph was all-in-all, and upon ‎his command everything was done in Potiphar’s house. And Joseph was eighteen years of age, ‎a youth of beautiful eyes and pleasant appearance, and there was not his like in the whole ‎land of Egypt. At that time when Joseph was in his master's house, coming in and going out ‎and attending to his master's affairs, Zulycah, his master's wife, lifted up her eyes unto Joseph, ‎and she beheld his comely appearance, and his beauty tempted her heart. And her soul ‎became attached unto Joseph, and she beguiled him and persuaded him day after day, but he ‎would not lift up his eyes to look at his master's wife. And Zulycah said unto him: How comely ‎is thy appearance and how graceful thy figure. Verily I have looked at all the servants, but I ‎could not find one as fair as thou art. And Joseph replied unto her: He who hath created me ‎hath created likewise all the sons of man. And she said unto him: How beautiful are those eyes ‎of thine and thou hast captivated with them all the inhabitants of Egypt, men and women ‎alike. And he said unto her: Verily they are beautiful while alive, but if thou wert to see them ‎in the grave thou wouldst tremble before them. And she continued: How pleasant and sweet ‎are thy words, do take the harp which is in the house and play with thy hands and let us hear ‎thy voice. And Joseph said: How pleasant and sweet are my words when I sing the praises and ‎the glory of my Lord.‎

“And you shall command,” that is what is written: “You would call and I would answer You, You would yearn [tikhsof] for Your handiwork” (Job 14:15). Regarding four matters the Holy One blessed be He longed for his handiwork. “Tikhsof” is nothing other than longing, as it is stated: “Because you longed [nikhsof nikhsafta]” (Genesis 31:30); “My soul longs [nikhsefa], indeed it pines” (Psalms 84:3). These are the four matters: The Holy One blessed be He bears [sovel] His world, as it is stated: “I have done and I will carry, I will bear [esbol] and I will rescue” (Isaiah 46:4), yet He commanded the sons of Kehat to bear Him, as it is stated: “But he did not give to the sons of Kehat, because the sacred service is upon them; they shall bear on the shoulder” (Numbers 7:9). Know, that, as it were, He bore them when they came to the Jordan, as it is stated: “The Jordan was overflowing all its banks” (Joshua 3:15), and the sons of Kehat were unable to cross. What did the Holy One blessed be He do? He bore them, as it is stated: “It shall be as the soles of the feet of the priests will rest” (Joshua 3:13). Rabbi Berekhya said: The Ark bears its bearers. The priests did not bear it, but rather, it bore them, as it is stated: “The soles of the feet of the priests were drawn up [onto dry ground]” (Joshua 4:18).
The Holy One blessed be He guards [meshamer] His world, as it is stated: “Behold, the Guardian of Israel neither slumbers nor sleeps. The Lord is your Guardian” (Psalms 121:4–5). And He said to Israel that they should guard Him, as it is stated: “And those encamped in front of the Tabernacle, to the east, in front of the Tent of Meeting: [Moses, and Aaron, and his sons, keeping [shomrim] the commission of the Sanctuary]” (Numbers 3:38). He illuminates the world, as it is written: “The earth shone with His glory” (Ezekiel 43:2). And He said of Israel: “They shall bring you pure olive oil.” That is, “yearn for Your handiwork.”
