What does Psalms Chapter 48 say, and which statements belong to its speaker?

The Latin incipit is Audite haec, omnes gentes. The separate heading describes worldly sinners not thinking of death or hell; the inscription is for Core's sons, unto the end. Nations and all inhabitants, earthborn and sons of men, rich and poor, are summoned. The speaker shall speak wisdom and meditate understanding, incline to a parable and open a proposition on the psaltery, not a harp.

He asks why fear in the evil day when heel's iniquity encompasses him. The separate note gives steps or ways, pride kicking neighbors, or sin found at death, interpreting the question as why indulge sins now that cause death-day fear and hell's peril. Those trusting strength and riches cannot have a brother or man redeem them or pay ransom and redemption price. A separate note says even a friend cannot rescue by price or labor. The verse mentions labor forever and life to the end; its note offers either inability to prolong earthly life to world's end or eternal sorrows of dying in sin. Another note reads the destruction statement as a question and says even wise and good people die.

Wise, senseless and foolish die, leaving riches to strangers. Sepulchres are lasting houses and lands named after them; the separate note says names on graves alone remain. Honor without understanding becomes comparison with senseless beasts. Their way is a stumblingblock but they delight in their mouth, separately explained as self-applause despite a wretched way.

They are laid in hell like sheep with death feeding, future just dominion in morning and decaying help in hell. The separate note interprets morning as resurrection judgment and passed earthly glory. The speaker says God will redeem his soul from hell when receiving him, not adding into glory. He forbids fear of increased riches and household glory, since none is taken at death. A person's soul will be blessed in lifetime and he will praise one doing well to him, yet he goes to fathers' generations and never sees light. The final comparison repeats honor without understanding and senseless beasts.
