'Whether' in the Bible

That through them I may prove Israel, whether they will keep the way of the LORD to walk therein, as their fathers did keep it, or not.

And they were to prove Israel by them, to know whether they would hearken unto the commandments of the LORD, which he commanded their fathers by the hand of Moses.

Speak, I pray you, in the ears of all the men of Shechem, Whether is better for you, either that all the sons of Jerubbaal, which are threescore and ten persons, reign over you, or that one reign over you? remember also that I am your bone and your flesh.

And they said unto him, Ask counsel, we pray thee, of God, that we may know whether our way which we go shall be prosperous.
