'Yours' in the Bible

Then the Spirit took control of Amasai, chief of the Thirty, and he said:We are yours, David,we are with you, son of Jesse!Peace, peace to you,and peace to him who helps you,for your God helps you.So David received them and made them leaders of his troops.

Yours, Lord, is the greatness and the power and the glory and the splendor and the majesty, for everything in the heavens and on earth belongs to You. Yours, Lord, is the kingdom, and You are exalted as head over all.
