Midrash su Proverbi 28:28

Thus it is written: "When the wicked rise, men hide themselves" (Prov. 28:28). Hence it was said: He who raises a wicked son or a wicked disciple eventually suffers dimness of sight. As for a wicked disciple, that follows from Ahijah the Shilonite, for he raised Jeroboam and his eyes grew dim, as it says: "Now Ahijah could not see, for his eyes were set by reason of age" (I Kings 14:4) – because he had raised up Jeroboam, a wicked disciple. As for a wicked son, that follows from Isaac.
