They are images of the Father and the Son, who destroyed impiety. They are also images of the prophets and apostles, for from both sides they aided the Sun.
Just as the evening lamp and the rooster’s crow, which disperse the darkness of night, assist the sun, so the prophets and apostles, who struggled with the darkness of impiety before and after Christ’s coming, aided the work of the Sun of righteousness.
But understand this also. John, whom the One who created his fiery mouth called a lamp, is also an image of Elijah. Elijah burned the ungodly with his tongue and punished them with drought and thirst by the flame of his mouth.
Moreover, the rooster that sings in the stillness of night is an image of John, who preached in the stillness of the wilderness.
If the lamp is brought in the evening hour, then the rooster, which sings only in the morning, cannot be heard at the same time as it, that is, by the lamp or in the evening.
But in John, the predawn voice was joined with the evening lamp, so as to bear witness to the coming of Elijah. Elijah is called the evening lamp because he is to appear at the end of the world. In a mystical manner he appeared in the person of John.
Therefore John is the voice, but the Word expressed by the voice is the Lord. The voice awakened them, the voice called them and raised them up, but the Word distributed His gifts to them.
