Job 5:5 - Matthew Poole's English Annotations on the Holy Bible

Whose harvest, which they now justly and confidently expect to reap, after all their cost and labour for that end, but are sadly and suddenly disappointed; which is a great aggravation of their misery. The hungry, i.e. the poor, whose necessities make them greedy and ravenous to eat it all up; and from whom he can never recover it, nor any thing in recompence of it. Out of the thorns, i.e. out of the fields, notwithstanding the strong thorn hedges wherewith it is enclosed and fortified, and all other dangers or difficulties which may be in their way. They will take it, though they be scratched and wounded by the thorns about it. The robbers; so called from their long hair, which such persons nourished, either because of their wild and savage kind of life, which made them neglect the trimming of their hair and body; or that they might look more terribly, and so affright all those who should endeavour to oppose them. Or, the thirsty, as the word may signify from another root. And so it answers well to the hungry, in the former branch. Swalloweth up greedily, and so as there is no hope of recovering it.
