He shall not be rich, i. e not abide rich, but shall become poor. Neither shall his substance continue; what he had gotten shall be taken from him. The perfection thereof, i.e. the perfection of his substance, or that complete estate and glory which he hath attained, shall not be continued to him and to his posterity. Or, neither shall their perfection (i.e. that prosperity, and wealth, and power wherein they placed their perfection or happiness) spread itself, or be propagated or spread abroad, but shall be diminished and taken away. It is a metaphor from a tree. Compare Job 8:16.
