'Affliction' in the Bible

For out of much affliction and anguish of heart I wrote unto you with many tears; not that ye should be grieved, but that ye might know the love which I have more abundantly unto you.

For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;

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