"When you are angry do not sin, but instead think of these things quietly as you go to bed."
-Psalm 4:4 (to be totally honest, I'm not sure of the translation because this one is from memory, but I have it in NIV below (: )
"Tremble and do not sin; when you are on your beds, search your hearts and be silent."
And NLT says "Don't sin by letting anger control you. Think about it overnight and remain silent."
This was always my favorite verse as a child! It was the first one I memorized by choice. I love the message and wisdom that comes with it (:
