'Know' in the Bible

the eyes of your understanding being enlightened so that you may know what is the hope which His call to you inspires, what the wealth of the glory of His inheritance in God's people,

You well know that whatever right thing any one does, he will receive a requital for it from the Lord, whether he is a slave or a free man.

And you masters, act towards your slaves on the same principles, and refrain from threats. For you know that in Heaven there is One who is your Master as well as theirs, and that merely earthly distinctions there are none with Him.

But in order that you also may know how I am doing, Tychicus our dearly-loved brother and faithful helper in the Lord's service will tell you everything.

I have sent him to you for the very purpose--that you may know about us and that he may encourage you.
