John Trapp on Psalms 49:18

Verſ. 18. Though whilſt be lived he bleſſed his ſoul] As that rich fool did, Luk. 12. and that King of France, who puffed up with the Marriage of his Siſter to the King of Spain, called himſelf by a new title, Treſ-bureuſe Roy, the thrice happy King; but was ſoon after accidentally ſlain by the Captain of his Guard running at Tilt with him, at the ſolemnizing of that ſame Marriage, in the very beginning of his ſuppoſed happineſs.

And men will praiſe thee when thou doeſt well to thy ſelf] Feathering thine own Neſt, and pampering thine own Carcaſs; thou ſhalt bee ſure of Paraſites, and Trencher-flies, who will highly commend thee, though againſt their own Conſciences, Rom. 1. ult. The world generally admireth the happineſs of ſuch as live at full, and ask what ſhould ſuch a one ayl? The Iriſh ask what they meant to dye?
