'Soothsayers' in the Bible

Therefore thou hast forsaken thy people the house of Jacob, because they be replenished from the east, and are soothsayers like the Philistines, and they please themselves in the children of strangers.

And when they shall say unto you, Seek unto the necromancers and unto the soothsayers, who chirp and who mutter, say, Shall not a people seek unto their God? Will they go for the living unto the dead?

And the spirit of Egypt shall fail in the midst of it, and I will destroy the counsel thereof; and they shall seek unto the idols and unto the conjurers, and unto the necromancers, and unto the soothsayers.
