Job 30:2

Yea, whereto might the strength of their hands profit me - There has been much difference of opinion respecting the meaning of this passage. The general sense is clear. Job means to describe those who were reduced by poverty and want, and who were without respectability or home, and who had no power in any way to affect him. He states that they were so abject and worthless as not to be worth his attention; but even this fact is intended to show how low he was himself reduced, since even the most degraded ranks in life did not show any respect to one who had been honored by princes. The Vulgate renders this, “The strength - virtus - of whose hands is to me as nothing, and they are regarded as unworthy of life.” The Septuagint, “And the strength of their hands what is it to me? Upon whom perfection - συντέλεια sunteleia - has perished.” Coverdale, “The power and strength of their hands might do me no good, and as for their age, it is spent and passed away without any profit.” The literal translation is, “Even the strength of their hands, what is it to me?” The meaning is, that their power was not worth regarding. They were abject, feeble, and reduced by hunger - poor emaciated creatures, who could do him neither good nor evil. Yet this fact did not make him feel less the indignity of being treated by such vagrants with scorn. In whom old age was perished - Or, rather, in whom vigor, or the power of accomplishing, anything, has ceased. The word כלח kelach, means “completion,” or the act or power of finishing or completing anything. Then it denotes old age - age as “finished” or “completed;” Job 5:26. Here it means the maturity or vigor which would enable a man to complete or accomplish anything, and the idea is, that in these persons this had utterly perished. Reduced by hunger and want, they had no power of effecting anything, and were unworthy of regard. […]
