Psalm 57 Jan. 31 For the Chief Musician. To the tune of Do Not Destroy. A poem by David, when he fled from Saul, in the cave.  1Be merciful to me, God, be merciful to me, for my soul takes refuge in You. Yes, in the shadow of Your wings I will take refuge, until disaster has passed. 2I cry out to God Most High, to God who accomplishes my requests for me. 3He will send from heaven and save me, He rebukes the one who is pursuing me. Selah. God will send out His grace and His truth. 4My soul is among lions. I lie among those who are set on fire, even the sons of men, whose teeth are spears and arrows, and their tongue a sharp sword. 5Be exalted, God, above the heavens! Let Your glory be above all the earth!  6They have prepared a net for my steps. My soul is bowed down, they dig a snare before me. They fall into its midst themselves. Selah. 7My heart is steadfast, God, my heart is steadfast. I will sing, yes, I will sing praises. 8Wake up, my glory! Wake up, psaltery and harp! I will wake up the dawn. 9I will give thanks to You, Lord, among the peoples, I will sing praises to You among the nations. 10For Your great grace reaches to the heavens, and Your truth to the skies. 11Be exalted, God, above the heavens. Let Your glory be over all the earth.   

Commentary

57:1 David didn’t see the physical cave he was hiding in (see Psalm title) as his refuge, but rather perceived God as his refuge. We may use medicines, doctors and all kinds of human things in our times of need, but we must perceive God as our true helper and final saviour rather than any of those things.
57:4 The vagabonds who supported David during his wilderness years were unspiritual men, and David so desperately longed for spiritual company. But David in his heart was ecstatic at God’s presence, and must’ve composed these words whilst laying with those men in the cave. This is a parade example to us of spiritual mindedness in unspiritual company.
