Psalm 5
Psa 5:1-12. Upon Nehiloth - flutes or wind instruments. The writer begs to be heard, on the ground of God's regard for His covenant-people and true worshippers as contrasted with His holy hatred to the wicked. He prays for divine guidance, on account of his watchful, malignant, and deceitful enemies; and for their destruction as being also God's enemies. At the same time he expresses his confidence that God will extend aid to His people.
