'Engaged' in the Bible

And he himself burned his sons in the fire in the Valley of Ben-Hinnom. And he practiced sorcery and divination, and he engaged in witchcraft and dealt with mediums and spiritists. And he did much evil in the eyes of Yahweh, to provoke him to anger.

And afterwards they made ready for themselves and for the priests; because the priests, the sons of Aaron, were engaged in offering up the burnt-offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests, the sons of Aaron.
