'Know' in the Bible

The eyes of your understanding being enlightened; that ye may 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 Christ, which passeth knowledge, that ye might be filled with all the fulness of God.

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

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

Whom I have sent unto you for the same purpose, that ye might know our affairs, and that he might comfort your hearts.
