The things [that] my soul refused to touch [are] as my sorrowful meat. Meaning either the above things, that which is unsavoury, and the white of an egg, of any other food, which in the time of his prosperity he would not touch with his fingers, much less eat, but now was glad of, and were his constant food in his present sorrowful circumstances; the sense given by some Jewish writers is, that what he disdained to touch or wipe his hands with formerly, he was glad to make use of as a tablecloth to eat his bread of sorrow upon; but it rather intends the insipid and disagreeable words of his friends, their doctrines, instructions, and exhortations they gave him, but were refused and rejected by him; and which he before compares to unsavoury food, the white of an egg, or the spittle of a dreaming man, or the dribble of a fool; and which were as much loathed and nauseated by him, as his food that was "loathed" by him , either because of his want of appetite, or because of the badness of it, such as were corrupt and "rotten", and even as the "excrements" of food ; those he refused to receive with as much indignation as he could such sort of food offered him; and therefore we find, that notwithstanding all that had been said to him, he continued in the same sentiment and disposition of mind, to desire death rather than life, as follows.
