'Know' in the Bible

to know also the love of the Christ that is exceeding the knowledge, that ye may be filled -- to all the fulness of God;

for this ye know, that every whoremonger, or unclean, or covetous person, who is an idolater, hath no inheritance in the reign of the Christ and God.

And that ye may know -- ye also -- the things concerning me -- what I do, all things make known to you shall Tychicus, the beloved brother and faithful ministrant in the Lord,

whom I did send unto you for this very thing, that ye might know the things concerning us, and that he might comfort your hearts.
