In Psalm 4, David is on the run, fleeing from his rebellious son Absalom. It's nighttime, and his mind is flooded with worries. He cries out to God for help. He's in a tight space (similar to Ps23, in the valley of the shadow of death), and God enlarges it for him, leads him through.

The trap is to think our situation will never get better... we should do as David, and think of all the tight places God has gotten us out of!

Absalom's council was filled with gaslighting fault-finders. In the New Testament, the pharisees similarly continually tried to provoke Jesus, trip him up, prove him wrong. In verse 2, David wonders, how long do I have to put up with this?

In verse 3 comes the remedy: God has set him apart, and hears when he calls! We can trust in God; as God's people, we may be down now, but he'll get us back up.

Verse 4 - be angry and don't sin. Proverbs 16:32, he who is slow to anger is better than he who is mighty!

Paul quotes verse 4 in Ephesians 4:26... as Christians today, we should work through our anger in a way that leads not into sin, giving no opportunity to the devil. Our anger should lead to redemption, to refinement. 

One thought... Lying in bed alone at night, your thoughts are clear and unfiltered. David asks God for his accusers to stop and ponder, and come to the truth. Sometimes we too need to stop talking, get alone with our thoughts and with God, and truly ponder things.
