'Whether' in the Bible

And while the people were in suspense and all were debating in their minds whether John might possibly be the Anointed One,

The Scribes and the Pharisees were on the watch to see whether He would cure him on the Sabbath that they might be able to bring an accusation against Him.

Then Jesus said to them, "I put it to you all whether we are allowed to do good on the Sabbath, or to do evil; to save a life, or to destroy it."

Consider therefore whether the light that is in you is anything but mere darkness.

And whether it be in the second watch or in the third that He comes and finds them so, blessed are they.

Or what king, marching to encounter another king in war, does not first sit down and deliberate whether he is able with ten thousand men to meet the one who is advancing against him with twenty thousand?
