Matthew Poole and continuators on Job 30:2

2. Yea, whereto might the strength of their hands profit me , in whom old age was perished ?

Nor was it strange that I did, or would, or might refuse to take them into any of my meanest services, because they were utterly impotent, and therefore unserviceable.

Or, bost, either 1. because they never attain to it, but are consumed by their lusts, or cut off for their wickedness by the just hand of God or men in the midst of their days. Or 2. because they had so wasted their strength and spirits by their evil courses, that when they came to old age, they were feeble and decrepit▪ and useless for any labour. Or 3. because they had not that prudence and experience which is proper and usual in that age, by which they might have been useful if not for work, yet to oversee and direct others in their work. But the words may be thus rendred, In whom vigorous age was perished, i. e. who were grown impotent for service. For the word here rendred old age, is used only here, and Iob 5. 26. where also it may be so rendred, Thou shalt come to thy grave in a vigorous or mature age, having the vigour of youth even in thine old age and until thy death, as Moses had. And if this word do signifie old age, yet it signifies not every, but only a flourishing and vigorous old age; as the Hebrews note, and the word may seem to imply: Whence the seventy Interpreters also render it perfection, to wit, of age, and of the endowments belonging to age.
