'Confidence' in the Bible

In this confidence, I was determined to come first to you, that you might have a second benefit;

And I wrote this very thing to you, so that, when I came, I wouldn't have sorrow from them of whom I ought to rejoice; having confidence in you all, that my joy would be shared by all of you.

Such confidence we have through Christ toward God;

We have sent with them our brother, whom we have many times proved earnest in many things, but now much more earnest, by reason of the great confidence which he has in you.

Yes, I beg you that I may not, when present, show courage with the confidence with which I intend to be bold against some, who consider us to be walking according to the flesh.

That which I speak, I don't speak according to the Lord, but as in foolishness, in this confidence of boasting.
