This was probably written on the same occasion as Psalm 34, when David fled from Saul to Philistine territory. He had to pretend insanity before Achish when some servants grew suspicious of him (1Sa 21:10-15).
Psalms 56:3-4
David stated, "What can mere mortals do to me?" How much harm can people do to us? They can inflict pain, suffering, and death. But no person can rob us of our souls or our future beyond this life. How much harm can we do to ourselves? The worst thing we can do is to reject God and lose our eternal life. Jesus said, "Don't be afraid of those who want to kill your body; they cannot touch your soul" (Mat 10:28). Instead, we should fear God, who controls this life and the next.
Psalms 56:8
Even in our deepest sorrow, God cares! Jesus reminded us further of how much God understands us—even the hairs on our head are all numbered (Mat 10:30). Often we waver between faith and fear. When you feel so discouraged that you are sure no one understands, remember that God knows every problem and sees every tear.
