Out of Jacob shall come he that shall have dominion,.... Meaning either David, or rather the Messiah; and so Jarchi interprets this of another ruler out of Jacob, even of the Messiah, of whom it is said, he shall have dominion from sea to sea; Ps 72:8,and shall destroy him, that remaineth of the city; chief city of Edom, or of any of the cities of it, signifying that there should be none left, see Ob 1:18, this is also applied to the days of the Messiah, in the ancient writings of the Jews .
Bemidbar Rabba, fol. 179.
