'Know' in the Bible

being enlightened in the eyes of your heart, so that ye should know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,

and to know the love of the Christ which surpasses knowledge; that ye may be filled even to all the fulness of God.

But in order that ye also may know what concerns me, how I am getting on, Tychicus, the beloved brother and faithful minister in the Lord, shall make all things known to you;

whom I have sent to you for this very thing, that ye may know of our affairs and that he may encourage your hearts.
