'Know' in the Bible

and during every day Mordecai is walking up and down before the court of the house of the women to know the welfare of Esther, and what is done with her.

And Esther calleth to Hatach, of the eunuchs of the king, whom he hath stationed before her, and giveth him a charge for Mordecai, to know what this is, and wherefore this is.

All servants of the king, and people of the provinces of the king, do know that any man and woman, who cometh in unto the king, unto the inner court, who is not called -- one law of his is to put them to death, apart from him to whom the king holdeth out the golden sceptre, then he hath lived; and I -- I have not been called to come in unto the king these thirty days.'
