'Whether' in the Bible

And these are those going up from Tel-Melah, Tel-Harsa, Cherub, Addan, Immer, and they have not been able to declare the house of their fathers, and their seed, whether they are of Israel:

And now, if to the king it be good, let search be made in the treasure-house of the king, that is there in Babylon, whether it be that of Cyrus the king there was made a decree to build this house of God in Jerusalem, and the will of the king concerning this thing he doth send unto us.'

and any who doth not do the law of thy God, and the law of the king, speedily is judgment done upon him, whether to death, or to banishment, or to confiscation of riches, and to bonds.'
