What does Psalms 49:14 mean?

They’re headed straight for the grave, like sheep being led to the slaughter. Death will feed on them. In the morning, good people will take their place, and their bodies will rot in the ground, far from their fancy homes. Psalms 49:14 - Modern Text Bible

(He’s using a vivid image: those who trust in wealth are like sheep going to be killed. Death claims them, and in the end, their possessions mean nothing.)
