“Be merciful unto me, O God, be merciful unto me: for my soul trusteth in Thee: yea, in the shadow of Thy wings will I make my refuge, until these calamities be overpast.” Psalm 57:1 (KJV)
Once again David realizes his need for the mercy of God. He is fleeing from king Saul. He is not fleeing because he is only fearful. He is fleeing, at least in part, because he fears he might end up needing to slay the king to save his own life. He is avoiding the possibility. For David to kill Saul, king of Israel, even for protecting his own life would be a sin against God.
We all need mercy, even in times of avoidance of what could happen. Maybe that is why Jabez prayed “…keep me from evil…” (1 Chronicles 4:10).
David hid in caves. Maybe he is hiding in a cave when he is praying this prayer; or shortly after leaving the cave. David trust in the God. The God [‘Elohiym]; the fulness of God.
As I read this Psalm I think of what Jesus said as He was preparing to leave the temple for the final time,
“O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!” Matthew 23:37 (KJV)
In the “shadow of Thy wings” is far better than anything our mind can imagine. When we flee from what we fear where do we flee? I choose to flee to Christ Jesus the fulness and the glory of God.
