John Trapp on Job 12:5

Verſe 5. He that is ready to ſlip with his feet] He who is in a declining, tottering condition, ready to fall and periſh under the burden of his afflictions, though formerly he was looked upon and made uſe of as a lamp or torch, yet when he is at an under, and brought low, is ſhamefully ſlighted by ſuch as have the world at will: like as a torch when waſted and waxen ſhort is caſt out of the hands, and trodden on with the feet of him that held it. The holieſt men, if afflicted, do but ſmother in ſtead of ſhining. When Chriſt himſelf was a man of ſorrows, he was therefore deſpiſed and rejected of men, who hid, as it were, their faces from him, and eſteemed him not, Iſa. 53.3. The Prodigals elder brother ſpeaks ſcornfully of him, becauſe poor, Luke 15.30. This thy ſon; he ſaith not, This my brother &c. Gregory ſaith, that the poor juſt man is here compared to a lamp extinct, becauſe he ſhineth inwardly by the vertue of an upright heart: but outwardly is as it were extinct, becauſe there is nothing outward to commend him; no glorious appearel, no goodly houſes, &c. whence they are ſlighted by the rich wretches of this world. But ſuch a lamp (ſaith he, following the Vulgar tranſlation) is ſet for an appointed time; that is, the day of judgment, when he ſhall ſhine moſt brightly, even as the Sun &c. when the worlds favourites ſhall be thruſt into utter darkneſſe.
