John Trapp on Psalms 49:6

Verſ. 6. They that truſt in their wealth] which was never yet true to thoſe that truſted in it: And yet it is wondrous hard to have wealth, and not in ſome meaſure to truſt in it, that is, to think our ſelves ſimply the better, and the ſafer for it, as our Saviour ſheweth, and this Diſciples after ſome wonderment, at length underſtood him; ſo Mark 10.23, 24. Hence that ſtrict charge, 1 Tim. 6.17.

And boaſt themſelves in the multitude of their riches] Contrary to Jer. 9.23. This Pſalm ſets forth the better gloriation of a Beleever in the grace of God, and in his bleſſed condition, wherein he is lifted up above the greateſt Worldings.
