Psalms 57:1-3

Introduction

David cries to God for mercy, with the strongest confidence of being heard, Psa 57:1-3; he describes his enemies as lions, Psa 57:4; thanks God for his deliverance, Psa 57:5; and purposes to publish the praises of the Lord among his people, Psa 57:6-11.

The title is, To the chief Musician, Al-taschith, (destroy not), a golden Psalms of David, (or one to be engraven), where he fed from Saul in the cave. It is very likely that this Psalm was made to commemorate his escape from Saul in the cave of En-gedi, where Saul had entered without knowing that David was there, and David cut off the skirt of his garment. And it is not improbable that, when he found that Saul was providentially delivered into his hand, he might have formed the hasty resolution to take away his life, as his companions counselled him to do; and in that moment the Divine monition came, אל תשצת al tascheth! Destroy not! lift not up thy hand against the Lord's anointed! Instead, therefore, of taking away his life, he contented himself with taking away his skirt, to show him that he had been in his power. When, afterwards, he composed the Psalm, he gave it for title the words which he received as a Divine warning. See the history 1 Samuel 24 (note): See also my note upon the fourth verse of that chapter, 1Sam 24:4 (note).

Verse 1

Be merciful unto me - To show David's deep earnestness, he repeats this twice; he was in great danger, surrounded by implacable enemies, and he knew that God alone could deliver him.

My soul trusteth in thee - I put my life into thy hand; and my immortal spirit knows no other portion than thyself.

In the shadow of thy wings - A metaphor taken from the brood of a hen taking shelter under her wings when they see a bird of prey; and there they continue to hide themselves till their evemy disappears. In a storm, or tempest of rain, the mother covers them with her wings to afford them shelter and defense. This the psalmist has particularly in view, as the following words show: "Until these calamities be overpast."
Verse 2

I will cry unto God most high - He is the Most High; and therefore far above all my enemies, though the prince of the power of the air be at their head.

Unto God, לאל lael, unto the strong Good, one against whom no human or diabolic might can prevail. David felt his own weakness, and he knew the strength of his adversaries; and therefore he views God under those attributes and characters which were suited to his state. This is a great secret in the Christian life; few pray to God wisely; though they may do it fervently.

That performeth all things for me - Who works for me; גמר gomer, he who completes for me, and will bring all to a happy issue.
Verse 3

He shall send from heaven, and save me - Were there no human agents or earthly means that he could employ, he would send his angels from heaven to rescue me from my enemies. Or, He will give his command from heaven that this may be done on earth.

Selah - I think this word should be at the end of the verse.

God shall send forth his mercy and his truth - Here mercy and truth are personified. They are the messengers that God will send from heaven to save me. His mercy ever inclines him to help and save the distressed. This he has promised to do; and his truth binds him to fulfll the promises or engagements his mercy has made, both to saints and sinners.
