'Joy' in the Bible

Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand.

And I wrote this same unto you, 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.

Therefore we were comforted in your comfort: yea, and exceedingly the more joyed we for the joy of Titus, because his spirit was refreshed by you all.

How that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality.
