'Whether' in the Bible

And these were they that went up from Tel-melah, Tel-harsha, Cherub, Addan, and Immer; but they could not show their fathers houses, and their seed, whether they were of Israel:

Now therefore, if it seem good to the king, let there be search made in the king's treasure-house, which is there at Babylon, whether it be so, that a decree was made of Cyrus the king to build this house of God at Jerusalem; and let the king send his pleasure to us concerning this matter.

And whosoever will not do the law of thy God, and the law of the king, let judgment be executed upon him with all diligence, whether it be unto death, or to banishment, or to confiscation of goods, or to imprisonment.
