Cosmas Indicopleustes, on Num 24:17

“I shall see him, but not now: I shall behold him, but not near. A STAR SHALL RISE out of Jacob and a sceptre shall spring up from Israel: and shall strike the chiefs of Moab, and shall waste all the children of Seth.”

“A star shall arise out of Jacob, there shall be raised up a man out of Israel—and he shall smite the princes of Moab—and destroy all the sons of Seth. By the sons of Sêth he means the whole world. And this is not applicable to anyone except the Lord Christ, for Sêth is by interpretation a foundation. Since therefore Cain and his seed perished utterly in the deluge, while Abel the younger died childless, Sêth was posterior to these, from whom both Noah and all the world are descended, and who is thus a foundation as it were of mankind. Moreover for this reason Adam, inspired by the deity, addressed him by the name of Sêth, that is, foundation; and therefore he said: And he will subdue all the sons of Seth, that is, the whole world. Now this is applicable to Christ, and to Him alone, whom all scripture ever keeps in view.”
