All the strength of the soul's mourning is from the third to the
thirtieth day, during which time she sits on the grave, still thinking
her beloved might yet return (to the body whence she departed). When she
notices that the color of the face is changed, she leaves and goes away;
and this is what is written (Job. xiv. 22), "But his flesh upon him
shall have pain, and his soul shall mourn over him." Then the mouth and
the belly quarrel with one another, the former saying to the latter,
"All I have robbed and taken by violence I deposited in thee;" and the
latter, having burst three days after its burial, saying to the former,
"There is all thou hast robbed and taken by violence! as it is written
(Eccles. xii. 6), 'The pitcher is broken at the fountain.'"
