Ambrose of Milan : Moses blessed this tribe, saying: Dan is a lion's cub that shall leap forth from Bashan (Deut. XXXII, 22), that is, from confusion. Hence, according to the Greek translation, we should understand that Dan himself became a serpent sitting on the way. Dan means judgement. And therefore, this tribe underwent a grave risk of judgement, as the serpent, Antichrist, slipped in and wounded it with his venoms. — On the Blessings of the Patriarchs, Chapter VII
