Whoso diggeth a pit shall fall therein,.... That devises mischief against others, it shall come upon himself. The allusion is to the digging of pits for catching wild beasts, which are slightly covered with earth; and which sometimes the pursuers, through inadvertency, fall into themselves; the passage seems to be taken from Psa 7:15; and he that rolleth a stone, it will return upon him; that rolls a stone up hill, if he does not take care, it will return back, and fall with great force upon himself; so the mischief which a wicked man labours hard at, as men do in digging a pit, or rolling a stone, in time rolls back upon themselves; the measure they mete out to others is measured to them. Jarchi makes mention of an "hagadah", or exposition, which illustrates this passage, by the case of Abimelech; who slew threescore and ten persons on one stone, and was himself killed with a piece of a millstone cast upon him, Jdg 9:18; this may put in mind of the fable of Sisyphus (o), feigned in hell to roll a great stone to the top of a mountain, which presently falling down on his head, made his labour fruitless. (o) "Aut petis aut urges ruitum, Sisyphe, saxum", Ovid. Metamorph. l. 4. v. 460.
