Psalms 49:6

They that trust in their wealth, and boast themselves in the multitude of their riches;

Ver. 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 ourselves simply the better and the safer for it, as our Saviour showeth, and his disciples, after some wonderment, at length understood him; so Mark 10:23,24. Hence that strict charge, 1 Timothy 6:17 .

And boast themselves in the multitude of their riches] Contrary to Jeremiah 9:23. This psalm sets forth the better gloriation of a believer in the grace of God, and in his blessed condition, wherein he is lifted up above the greatest worldlings.
