A.T. Robertson Commentary Revelation 19:16

"And he hath on his garment and on his thigh a name written, KINGS OF KINGS, AND LORD OF LORDS." — Revelation 19:16 (ASV)

And on his thigh (κα επ τον μηρον αυτου). "Even upon his thigh." Old word, here alone in N.T.

King of kings, and Lord of lords (Βασιλευς βασιλεων κα Κυριος κυριων). The title already given to the Lamb in 17:14, but in reverse order. See the same idea in 1 Timothy 6:15.
