They devise injustice and say, “We have perfected a secret plan.” For the inner man and the heart are mysterious.

John Calvin Reformed @genevareformer

PSALM 64 This psalm expresses the language of complaint and prayer. David, in order that he may incline God to compassionate his case, dwells upon the injustice and cruelty, the intrigues and deceitfulness of his enemies. At the close, his eyes are directed to God, in the anticipation of a joyful deliverance from their hands. To the chief musician. A Psalm of David. Psalm 64:1-6 1.

C.H. Spurgeon Reformed Baptist @princeofpreachers

They search out iniquities. Diligently they consider, invent, devise, and seek for wicked plans to wreak their malice. These are no common villains, but explorers in iniquity, inventors and concoctors of evil. Sad indeed it is that to ruin a good man the evil disposed will often show as much avidity as if they were searching after treasure.

Matthew Henry Presbyterian @wholebiblehenry

David, in these verses, puts in before God a representation of his own danger and of his enemies' character, to enforce his petition that God would protect him and punish them. I. He earnestly begs of God to preserve him (Psa 64:1, Psa 64:2): Hear my voice, O God!
