Clement of Alexandria — on Rev 5:6 (The Stromata Book 5)

“The golden lamp conveys another enigma as a symbol of Christ, not in respect of form alone, but in his casting light, "at sundry times and divers manners," on those who believe on Him and hope, and who see by means of the ministry of the First-born. And they say that the seven eyes of the Lord "are the seven spirits resting on the rod that springs from the root of Jesse."”
