'Omens' in the Bible

There must never be found among you anyone who sacrifices his son or daughter in fire, practices divination, interprets omens, practices sorcery,

who frustrates the omens of idle talkers, and drives diviners mad, who turns back the wise, and makes their knowledge foolish;

because false messiahs and false prophets will appear and produce signs and omens to deceive, if possible, the elect.
