'Know' in the Bible

I pray that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints,

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

For this you know with certainty, that no immoral or impure person or covetous man, who is an idolater, has an inheritance in the kingdom of Christ and God.

But that you also may know about my circumstances, how I am doing, Tychicus, the beloved brother and faithful minister in the Lord, will make everything known to you.

I have sent him to you for this very purpose, so that you may know about us, and that he may comfort your hearts.
