'Whether' in the Bible

For ask now of the days that are past, which were before thee, since the day that God created man on the earth, and from one end of the heavens to the other end of the heavens, whether there hath been anything as this great thing is, or if anything hath been heard like it?

And thou shalt remember all the way which Jehovah thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments or not.

thou shalt not hearken unto the words of that prophet, or that dreamer of dreams; for Jehovah your God proveth you, to know whether ye love Jehovah your God with all your heart and with all your soul.

And this shall be the priest's due from the people, from them that sacrifice a sacrifice, whether ox, or sheep: they shall give unto the priest the shoulder, and the jawbones, and the maw.

He that is a eunuch, whether he have been crushed or cut, shall not come into the congregation of Jehovah.
