'Know' in the Bible

For I want you to know how great a struggle I have for you, for those in Laodicea, and for all who have not seen me in person.

Masters, supply your slaves with what is right and fair, since you know that you too have a Master in heaven.

Your speech should always be gracious, seasoned with salt, so that you may know how you should answer each person.

I have sent him to you for this very purpose, so that you may know how we are and so that he may encourage your hearts.
