In chapter 10 of 2 Samuel we read of several encounters David has with his enemies. The enemies of the Israelites combined forces and came against Israel but when they engaged David’s army they fled from them. The Army listened to Joab’s exhortation. He told them, “Be strong. We must fight bravely for our people and the cities of our God.”

Then again, a larger coalition gathered against David’s army. David himself led the charge and completely destroyed the advancing enemy.  Verse 18 says, “David killed seven hundred Aramean chariot drivers and forty thousand Aramean horsemen. He also killed Shobach, the commander of the Aramean army.” The enemy forces then fled from David and his men. All his enemies turned tail and ran.
I wonder if David’s Psalm 21 is about this. He writes: “Although they scheme and plan evil against you, they will not succeed. They turn their backs and flee because you aim your bow at their faces.”

Maybe Psalm 64 is about this also. We read, “But God shall shoot at them with an arrow; suddenly shall they be wounded. So they shall make their own tongue to fall upon themselves: all that see them shall flee away. And all men shall fear, and shall declare the work of God; for they shall wisely consider of his doing.”

Psalm 68 is David’s psalm also. He might be referring to this here. He says, “God shall arise, his enemies shall be scattered; and those who hate him shall flee before him!”

David’s son, Solomon, probably said it best in Proverbs 28:1. He writes, “The wicked flee when no one pursues, but the righteous are bold as a lion.”
