'Thine' in the Bible

Forasmuch as thou art sent of the king, and of his seven counsellers, to inquire concerning Judah and Jerusalem, according to the law of thy God which is in thine hand;

And thou, Ezra, after the wisdom of thy God, that is in thine hand, set magistrates and judges, which may judge all the people that are beyond the river, all such as know the laws of thy God; and teach ye them that know them not.
