Psalms 36:1-4

1 Transgression speaks to the wicked deep in their hearts; there is no fear of God before their eyes.
2 For they flatter themselves in their own eyes that their iniquity cannot be found out and hated.
3 The words of their mouths are mischief and deceit; they have ceased to act wisely and do good.
4 They plot mischief while on their beds; they are set on a way that is not good; they do not reject evil.

Psalms 36:1-4 Meaning and Commentary

To the chief Musician, [a Psalm] of David, the servant of the Lord. This title, which the psalmist takes to himself, regards him not only as a creature, every man being the servant of the Lord as such, of right, though not in fact; but as a king, he being a minister of God for good to good men, and for evil to evil men; and also may respect him as a renewed man; and it is here used in opposition to and distinction from the wicked, who are the servants of sin and Satan, of whom he speaks in this psalm. The Syriac and Arabic versions in their titles suggest that this psalm was written when David was persecuted by Saul, and which is the sense of some interpreters; but R. Obadiah thinks Ahithophel is designed by the wicked man in it; and so it was penned on account of Absalom's rebellion.
