Exodus 34:6 is a key OT passage that the writers of Scripture refer to time and time again. It’s a passage that puts the character of the LORD on display: "The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness…” David draws our attention to the steadfast love and faithfulness of the LORD at the beginning and end of Psalm 57 (v.v. 3,10). This psalm is David’s lament as he cries out to the LORD for help (v.4,6) and protection. What started out as a relationship filled with appreciation and love between David and Saul (1 Samuel 16:20-23) has now turned into David on the run from Saul, hiding in a cave, and fearing for his life. The culprit: Saul’s jealousy of David’s success (1 Samuel 18:6-8). Even in the slightest bit, the jealousy we experience is poisonous and left unchecked, it is capable of destroying the beauty and harmony of our closest relationships. David is right to lament “what once was” and seek refuge and comfort in the LORD’s protection.
