'Know' in the Bible

And Mordecai walked every day before the court of the women's house, to know how Esther did, and what should become of her.

Then Esther called for Hatach, one of the king's chamberlains, whom he had appointed to wait upon her, and gave him a commandment to Mordecai, to know what it was, and why it was.

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.
