'Familiar' in the Bible

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

He made his son to pass through the fire, and practiced sorcery, and used enchantments, and dealt with those who had familiar spirits, and with wizards: he worked much evil in the sight of Yahweh, to provoke him to anger.

Moreover those who had familiar spirits, and the wizards, and the teraphim, and the idols, and all the abominations that were seen in the land of Judah and in Jerusalem, did Josiah put away, that he might confirm the words of the law which were written in the book that Hilkiah the priest found in the house of Yahweh.
