Tradition varies respecting the tragic end of Esau. The Book of Jasher (chap. 56, v. 64) and the Targum of Jonathan (in Vayechi) both say that Cushim the son of Dan slew Esau at the burial, not of Isaac, but of Jacob, because he sought to hinder the funeral obsequies, disputing the title to the sepulchre.
"Oh, that I had wings like a dove! for then I would fly away, and be at rest" (Ps. lv. 6). This is spoken of Abraham. But why like a dove? Rabbi Azariah, in the name of Rabbi Yudan, says, "Because all birds when tired rest on a rock or on a tree, but a dove, when tired of flying, draws in one wing to rest it, and continues her flight with the other."

The Holy One—blessed be He!—said unto Abraham, "What should I tell thee? and with what shall I bless thee? Shall I tell thee to be perfectly righteous, or that thy wife Sarah be righteous before me? That ye both are already. Or shall I say that thy children shall be righteous? They are so already. But I will bless thee so that all thy children which shall in future ages come forth from thee shall be just like thee." Whence do we learn this? From Gen xv. 5: "And he said unto him, So (like thee) shall thy seed be."

"Every man ... by his own standard" (Num. ii. 2). The several princes of Israel selected the colors for their banners from the color of the stones that were upon the breastplate of Aaron. From them other princes have learned to adorn their standards with different distinguishing colors. Reuben had his flag red, and leaves of mandrakes upon it. Issachar had his flag blue, and the sun and moon upon it. Naphtali had on his flag an olive tree, for this reason that (Gen. xlix. 20) "Out of Asher his bread shall be fat."

"And Abraham rose up early and saddled his ass" (Gen. xxii. 3). This is the ass on which Moses also rode when he came into Egypt; for it is said (Exod. iv. 20), "And Moses took his wife and his sons, and set them upon an ass." This is the ass on which the Son of David also shall ride; as it is said (Zech, ix. 9), "Poor, and riding upon an ass."
