Revelation 2:18

Thyatira was a city of Mysia or Lydia, not far from Philippi, the chief city of Macedonia; for Lydia, who traded in purple, and was of this city, went to Philippi to trade, as we read, Acts 16:12,14. Eyes like unto a flame of fire: see Revelation 1:14,15: it signifies either angry eyes, or quick and piercing eyes. The comparing of his feet to fine brass, seemeth to signify both the purity and holiness of his ways and methods of providence, and also his firmness and steadiness in them.
