'Whether' in the Bible

And it came to pass as they spoke daily to him, and he hearkened not to them, that they informed Haman, to see whether Mordecai's matters would stand; for he had told them that he was a Jew.

All the king's servants and the people of the king's provinces do know that whoever, whether man or woman, shall come to the king into the inner court, who is not called, there is one law, to put him to death, except such to whom the king shall hold out the golden sceptre, that he may live; and I have not been called to come in unto the king these thirty days.

For if thou altogether holdest thy peace at this time, then shall there arise relief and deliverance to the Jews from another place; but thou and thy father's house shall perish. And who knows whether thou art not come to the kingdom for such a time as this?
