And they wished to speak one to another in the language of his fellow-countryman, but one did not understand the language of his fellow. What did they do? Every one took his sword, and they fought one another to destroy (each other), and half the world fell there by the sword, and thence the Lord scattered them upon the face of all the earth, as it is said, "So the Lord scattered them abroad on that account, upon the face of all the earth" (Gen. 11:8).
Rabbi Meir said: Esau, the brother of Jacob, saw the coats of Nimrod, and in his heart he coveted them, and he slew him, and took them from him. Whence (do we know) that they were desirable in his sight? Because it is said, "And Rebecca took the precious raiment of Esau, her elder son" (Gen. 27:15). When he put them on he also became, by means of them, a mighty hero, as it is said, "And Esau was a cunning hunter" (Gen. 25:27). And when Jacob went forth from the presence of Isaac, his father, he said: Esau, the wicked one, is not worthy to wear these coats. What did he do? He dug in the earth and hid them there, as it is said, "A noose is hid for him in the earth" (Job 18:10).
