Tower of Edar - Literally, the tower of the flock, and so translated Micah 4:8. It is supposed that this tower was about a mile from Bethlehem, and to have been the place where the angels appeared to the shepherds. The Targum of Jonathan expressly says: "It is the place in which the King Messiah shall be manifested in the end of days." By the tower of the flock we may understand a place built by the shepherds near to some well, for the convenience of watering their flocks, and keeping watch over them by night.

And Israel journeyed,.... Having stayed near Bethlehem, as it is said, about two months (h); this is the first time Jacob is by Moses called Israel, after this name, was given him; the reason of which the Jews say is, because he bore the death of Rachel with so much patience:
and spread his tent beyond the tower of Eder; which was a place of pasturage, and fit for his flocks, see Micah 4:8; it was about a mile from Bethlehem to the south (i), and is supposed to be the place where the shepherds were watching their flocks, when the angel reported to them the birth of Christ, Luke 2:8; pretty remarkable are the words added here in the Targum of Jonathan,"the place from whence the King Messiah will be revealed in the end of days.''

What a sore affliction Reuben's sin was, is shown, " and Israel heard it." No more is said, but that is enough. Reuben thought that his father would never hear of it; but those that promise themselves secrecy in sin, are generally disappointed. The age and death of Isaac are recorded, though he died not till after Joseph was sold into Egypt. Isaac lived about forty years after he had made his will, Genesis 27:2. We shall not die an hour the sooner, but much the better, for timely setting our hearts and houses in order. Particular notice is taken of the agreement of Esau and Jacob at their father's funeral, to show how God had wonderfully changed Esau's mind. It is awful to behold relations, sometimes for a little of this world's goods, disputing over the graves of their friends, while they are near going to the grave themselves.

Israel, a prince with God, yet dwells in tents; the city is reserved for him in the other world.
