Sirach 11:25

25 In the day of prosperity there is a forgetfulness of affliction: and in the day of affliction there is no more remembrance of prosperity.

Sirach 11:25 In-Context

23 Say not, What profit is there of my service? and what good things shall I have hereafter?
24 Again, say not, I have enough, and possess many things, and what evil shall I have hereafter?
25 In the day of prosperity there is a forgetfulness of affliction: and in the day of affliction there is no more remembrance of prosperity.
26 For it is an easy thing unto the Lord in the day of death to reward a man according to his ways.
27 The affliction of an hour maketh a man forget pleasure: and in his end his deeds shall be discovered.
