'Whether' in the Bible

"Yes, ask, please, about former days that {preceded you} from the day that God created humankind on the earth; [ask even] from [one] end of the heaven up to the [other] end of heaven {whether anything ever happened} like this great thing or {whether anything like it was ever heard}.

And you shall remember all [of] the way that Yahweh your God led you [during] these forty years in the desert in order to humble you and to test you to know what [is] in your heart, whether you would [diligently] keep his commandments or not.

you must not listen to the words of that prophet or to that dreamer, for Yahweh your God {is testing you to know whether you love} Yahweh your God with all of your heart and with all [of] your inner self.

Now this shall be the share of the priest from the people, from {those who sacrifice the sacrifice}, [whether it is] an ox, sheep, or goat, and they shall give the priest the shoulder and the jawbones and the stomach.
