Whether divination by auguries, omens, and by like observations of external things is unlawful?

❌ Objection 1 : It would seem that divination by auguries, omens, and by like observations of external things is not unlawful. If it were unlawful holy men would not make use thereof. Now we read of Joseph that he paid attention to auguries, for it is related (Gn. 44:5) that Joseph's steward said: "The cup which you have stolen is that in which my lord drinketh and in which he is wont to divine [augurari]": and he himself afterwards said to his brethren (Gn. 44:15): "Know you not that there is no one like me in the science of divining?" Therefore it is not unlawful to make use of this kind of divination.

❌ Objection 2 : Further, birds naturally know certain things regarding future occurrences of the seasons, according to Jer. 8:7, "The kite in the air hath known her time; the turtle, the swallow, and the stork have observed the time of their coming." Now natural knowledge is infallible and comes from God. Therefore it seems not unlawful to make use of the birds' knowledge in order to know the future, and this is divination by augury.

❌ Objection 3 : Further, Gedeon is numbered among the saints (Heb. 11:32). Yet Gedeon made use of an omen, when he listened to the relation and interpreting of a dream (Judges 7:15): and Eliezer, Abraham's servant, acted in like manner (Gn. 24). Therefore it seems that this kind of divination is not unlawful.
