'Spirits' in the Bible

On the twenty-third day of the seventh month, King Solomon sent the people back home, and they returned rejoicing and in good spirits because of the goodness that the LORD had shown to David, to Solomon, and to his people Israel.

He also made his children to pass through the fire in the valley of the son of Hinnom; and he practised augury, and used enchantments, and practised sorcery, and dealt with them that had familiar spirits, and with wizards: he wrought much evil in the sight of Jehovah, to provoke him to anger.
