'Familiar' in the Bible

So Jehu smote all that remained of the house of Ahab in Jezreel, and all his great men, and his familiar friends, and his priests, until he left him none remaining.

And he made his son pass through the fire, and observed times, and used enchantments, and dealt with familiar spirits and wizards: he wrought much wickedness in the sight of the LORD, to provoke him to anger.

Moreover the workers with familiar spirits, and the wizards, and the images, and the idols, and all the abominations that were spied in the land of Judah and in Jerusalem, did Josiah put away, that he might perform the words of the law which were written in the book that Hilkiah the priest found in the house of the LORD.
