Jeremias 13
Bede
Jeremias 13:23
Also, he showed so much love in his religion that, leaving behind a queen's court, he came from the farthest regions of the world to the Lord's temple. Hence, as a just reward, while he sought the interpretation of something that he was reading, he found Christ, whom he was seeking. Furthermore, as Jerome says, he found the church's font there in the desert, rather than in the golden temple of the synagogue. For there in the desert something happened that Jeremiah declared was to be wondered at, an Ethiopian changed his skin, that is, with the stain of his sins washed away by the waters of baptism, he went up, shining white, to Jesus. — Commentary on Acts 8:27a
