'Know' in the Bible

I want you to know, brothers and sisters, that my situation has actually turned out to advance the gospel:

The latter do so from love because they know that I am placed here for the defense of the gospel.

for I know that this will turn out for my deliverance through your prayers and the help of the Spirit of Jesus Christ.

Now if I am to go on living in the body, this will mean productive work for me, yet I don't know which I prefer:

And since I am sure of this, I know that I will remain and continue with all of you for the sake of your progress and joy in the faith,

But you know his qualifications, that like a son working with his father, he served with me in advancing the gospel.

So I hope to send him as soon as I know more about my situation,

My aim is to know him, to experience the power of his resurrection, to share in his sufferings, and to be like him in his death,

I have great joy in the Lord because now at last you have again expressed your concern for me. (Now I know you were concerned before but had no opportunity to do anything.)

And as you Philippians know, at the beginning of my gospel ministry, when I left Macedonia, no church shared with me in this matter of giving and receiving except you alone.
