'Inheritance' in the Bible

Samuel took the flask of oil, poured it out on Saul’s head, kissed him, and said, “Hasn’t the Lord anointed you ruler over His inheritance?

Now, may my lord the king please hear the words of his servant: If it is the Lord who has incited you against me, then may He accept an offering. But if it is people, may they be cursed in the presence of the Lord, for today they have driven me away from sharing in the inheritance of the Lord saying, ‘Go and worship other gods.’
