'Whether' in the Bible

“For cross over to the coasts of Kittim (Cyprus) [to the west] and see,Send also to Kedar (Arabia) [to the east] and carefully observe and considerAnd see whether there has been such [a thing] as this!

For you will no longer remember the oracle of the Lord, because every man’s own word will become the oracle, [for as they mockingly call all prophecies oracles, whether good or bad, so will it prove to be to them; God will take them at their own word]; and you have perverted the words [not of a lifeless idol, but] of the living God, the Lord of hosts, our God.

And as for you, do not listen to your [counterfeit] prophets, your diviners, your dreams and dreamers, your soothsayers or your sorcerers, who say to you, ‘You will not serve the king of Babylon.’

‘Ask now, and seeWhether a man can give birth [to a child].Why then do I see every manWith his hands on his loins, as a woman in labor?Why have all faces turned pale?

Whether it is pleasant or unpleasant, we will listen to and honor the voice of the Lord our God to whom we are sending you, so that it may go well with us when we listen to the voice of the Lord our God.”
