'Theirs' in the Bible

Now the servant who had gone to get Micaiah said to him, See now, all the prophets with one voice are saying good things to the king; so let your words be like theirs, and say good things.

And they gave up the house of the Lord God of their fathers, and became worshippers of pillars of wood and of the images; and because of this sin of theirs, wrath came on Judah and Jerusalem.

In addition, he gave orders to the people of Jerusalem to give to the priests and Levites that part which was theirs by right, so that they might be strong in keeping the law of the Lord.
