Matthew Poole and continuators on James 1:10

10 But the rich in that he is made low , because as the flower of the grass he shall pass away .

Viz. Brother, he that is in an high, honourable, or plentiful Condition in the World.

Supply from the former Verse, let him rejoyce in that he is made low; not as to his outward state (for he is supposed to be rich still) but his inward Disposition, and frame of Mind, God having given him a lowly Heart in an high Condition, and thereby prepared him for the Cross, tho as yet he be not under it

The Reason why the rich Brother should be humble in his greatest Abundance, viz. because of the uncertainty of his enjoying what at present he possesseth; he is neither secure of his Life, nor his Wealth; he, and his Enjoyments pass away, and his Pomp vanisheth as easily as the Flower of the Grass, which fades as soon as it flourisheth.
