Exegetical and Hermeneutical Commentary of Numbers 13:13
Of the tribe of Asher, Sethur the son of Michael.
Verse 13. Sethur, the son of Michael.] It would have been strange had the numerous searches after the explanation of the mystical number 666, Re 13:18; Re 17:5, met with nothing to their purpose in the name of this son of Michael. Sethur, from sathar, to hide or conceal, signifies hidden or mysterious, and includes in it the numerical letters of the No. 666: 60, + 400, + 6, + 200, = 666. But of what utility can such expositions be to any subject of history or theology?

Sethur = hidden, or mystical: by Gematria = 666 (App-10). Probably marking the ringleader of the Provocation.
