'Know' in the Bible

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

Then called Esther for Hathach, one of the king's chamberlains, whom he had appointed to attend upon her, and charged him to go to Mordecai, to know what this was, and why it was.

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