A.T. Robertson Commentary Revelation 2:18

"And to the angel of the church in Thyatira write: These things saith the Son of God, who hath his eyes like a flame of fire, and his feet are like unto burnished brass:" — Revelation 2:18 (ASV)

In Thyatira (εν Θυατειροις). Some forty miles south-east of Pergamum, a Lydian city on the edge of Mysia, under Rome since B.C. 190, a centre of trade, especially for the royal purple, home of Lydia of Philippi (Acts 16:14f.), shown by inscriptions to be full of trade guilds, Apollo the chief deity with no emperor-worship, centre of activity by the Nicolaitans with their idolatry and licentiousness under a "prophetess" who defied the church there. Ramsay calls it "Weakness Made Strong" (op. cit., p. 316).

The Son of God (ο υιος του θεου). Here Jesus is represented as calling himself by this title as in Joh 11:4 and as he affirms on oath in Mt 26:63f. "The Word of God" occurs in 19:13.

His eyes like a flame of fire (τους οφθαλμους αυτου ως φλογα πυρος). As in 1:14.

His feet like burnished brass (ο ποδες αυτου ομοιο χαλκολιβανω). As in 1:15.
