Psalm 73:15-17

Amplified Bible

¹⁵ 
If I had said, “I will say this,” [and expressed my feelings],
I would have betrayed the generation of Your children.
¹⁶ 
When I considered how to understand this,
It was too great an effort for me and too painful
¹⁷ 
Until I came into the sanctuary of God;
Then I understood [for I considered] their end.
