'Know' in the Bible

having the eyes of your heart enlightened, that ye may know what is the hope of his calling, what the riches of the glory of his inheritance in the saints,

and to know the love of Christ which passeth knowledge, that ye may be filled unto all the fulness of God.

For this ye know of a surety, that no fornicator, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and God.

But that ye also may know my affairs, how I do, Tychicus, the beloved brother and faithful minister in the Lord, shall make known to you all things:

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