For Yahweh is righteous. He loves righteousness. The upright shall see his face. For the Chief Musician; upon an eight-stringed lyre. A Psalm of David.

For the choir director; upon an eight-stringed lyre. A Psalm of David.Help, Lord, for the godly man ceases to be,For the faithful disappear from among the sons of men.
