'Know' in the Bible

having the eyes of your hearts enlightened, that you may know what is the hope of his calling, and what are the riches of the glory of his inheritance in the saints,

and to know Christ's love which surpasses knowledge, that you may be filled with all the fullness of God.

Know this for sure, that no sexually immoral person, nor unclean person, nor covetous man, who is an idolater, has any inheritance in the Kingdom of Christ and God.

But that you also may know my affairs, how I am doing, Tychicus, the beloved brother and faithful servant in the Lord, will make known to you all things;

whom I have sent to you for this very purpose, that you may know our state, and that he may comfort your hearts.
