Psalm 3 is a psalm of David, written during his flight from his son Absalom (2 Samuel 15-18). It is a prayer of confidence in God's protection. David begins by acknowledging the multitude of his enemies and their taunts that God will not deliver him. However, he expresses his trust in the Lord as his shield and the one who lifts his head high. David recounts how he cried out to the Lord and was answered from His holy hill. Despite the danger, David lies down and sleeps, waking again because the Lord sustains him. He concludes by affirming that salvation belongs to the Lord and asking for His blessing on His people. This psalm highlights the themes of trust in God's protection and deliverance in times of trouble.
