and Jacob would have nothing. So Esau took Isaac's wealth and gave Jacob the land of Israel and the Cave of Machpelah, and they wrote a perpetual deed between them. Jacob then told Esau to leave the land, and Esau took his wives, children, and all that he had, as reports, "And Esau took his wives . . . and all his possessions which he had gathered in the land of Canaan, and went into a land away from his brother Jacob." As a reward, God gave Esau a hundred provinces from Seir to Magdiel, as reports, and Magdiel is Rome. Then Jacob dwelt safely and in peace in the land of Israel.

Similar uses appear in to teach Dathan and Abiram's enduring wickedness, in to teach Ahaz's enduring
