About in the middle of Psalm 119 we are reading three times about affliction.  

The Psalmist speaks about affliction in the verses 67, 71 and 75.

1.  Psalm 119:67

“Before I was afflicted I went astray, but now  I obey your word.”

2.  Psalm 119:71

“It was good for me to be afflicted so that I might learn your decrees.” Read also the next verse! 

3. Psalm 119:75

“I know, O LORD, that your laws are righteous, and in faithfulness you have afflicted  me.”
