'Omen' in the Bible

Indeed, O Lord, you have abandoned your people, the descendants of Jacob. For diviners from the east are everywhere; they consult omen readers like the Philistines do. Plenty of foreigners are around.

the mighty men and warriors, judges and prophets, omen readers and leaders,

the Lord said, “As My servant Isaiah has gone naked and barefoot three years as a sign and omen against Egypt and Cush,

who frustrates the omens of the empty talkers and humiliates the omen readers, who overturns the counsel of the wise men and makes their advice seem foolish,

But approach, you sons of omen readers, you offspring of adulteresses and prostitutes!
