1 Samuel 24 | Psalm 57 | 1 Samuel 25
David has opportunity to kill Saul in the cave, but he refuses to lift his hand against the king that God had anointed. This will be his position as long as Saul is king in Israel.
Nabal is a foolish man who offends David in his pride, but his wife Abigail is a wise lady who intervenes before David takes revenge on her husband. Within 10 days Nabal is dead at the hand of God, and David takes Abigail as one of his wives.
God said that vengeance belongs to Him (Deuteronomy 32:35), and this was true in the life of David, and it is true for us. Paul said in Romans 12:19 that we should not avenge ourselves, but give God that responsibility when we have been wronged or harmed.
