Job 20:13 [Though] he spare it, and forsake it not; but keep it still within his mouth:
Ver. 13. Though he spare it, and forsake it not] This is the same in sense with the former verse, and the second time repeated, that Job might know that he was the man here meant; Ut qui in malis artibus sibi placuisset, saith Merlin, as one who took pleasure in raising himself upon another's ruins. And another good note the same author giveth here, viz. That as anything is more sweet and delectable to the sensual appetite, so much the more should we suspect it, as fearing a snare laid for us therein, by that old manslayer. Vipera later in veprecula. Diabolus capite blanditur, ventre oblectat, cauda ligat. Divorce the flesh from the devil, and then there is no great danger.
But keep it still within his mouth] And will not be drawn to spit it out by confession, and to carry it through the dung port of his mouth into the brook Kidron, which was the town ditch. Satan knows there is no way to purge the sick soul but upwards. He therefore laboureth to hold his lips close, that the soul may not unburden itself, and God come in with his cordials of comfort. See Trapp on " Job 20:12 "
