'Confidence' in the Bible

And in this confidence I was minded to come first unto you, that ye might have a second benefit;

And I wrote this very thing, lest, when I came, I should have sorrow from them of whom I ought to rejoice; having confidence in you all, that my joy is the joy of you all.

And such confidence have we through Christ to God-ward:

and 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 hath in you.

lest by any means, if there come with me any of Macedonia and find you unprepared, we (that we say not, ye) should be put to shame in this confidence.

yea, I beseech you, that I may not when present show courage with the confidence wherewith I count to be bold against some, who count of us as if we walked according to the flesh.

That which I speak, I speak not after the Lord, but as in foolishness, in this confidence of glorying.
