'People of Israel' in the Bible

He went up to the altar he had made in Beth-el on the fifteenth day of the eighth month, the month fixed by him at his pleasure; and he gave orders for a feast for the people of Israel, and went up to the altar, and there he made the smoke of his offerings go up.

Then there was a division among the people of Israel; half the people were for making Tibni, son of Ginath, king, and half were supporting Omri.
