John Gill Commentary Ezekiel 23:34

"Thou shalt even drink it and drain it out, and thou shalt gnaw the sherds thereof, and shalt tear thy breasts; for I have spoken it, saith the Lord Jehovah." — Ezekiel 23:34 (ASV)

You shall even drink it, and suck it out The very dregs of it, that which lies at the bottom, which is the most nauseous and the most pernicious; not through love to it, but through force, shall be obliged to it; see (Psalms 75:8).

And you shall break the sherds thereof and suck them, so that not a drop of the liquor shall be lost; even what has penetrated into the earthen vessel, which this cup is supposed to be; and therefore it shall be broken to pieces, and these pieces sucked, that all may be got out; suggesting that there will be no abatement of the punishment, it shall be endured to the utmost: or it may be an allusion to drunkards, who, having drunk up their liquor, and become drunk, break their glasses, pots, and cups, and to which the next clause agrees.

And pluck off your own breasts as men in their drunken fits, being like mad men, tear their own flesh; and so the Targum paraphrases it, ``you shall tear your flesh;'' so the Jews, under punishment for sin, and pressed with the guilt of it, through indignation at themselves should tear their flesh, and particularly pluck off their breasts: the allusion is to fornication, to which idolatry is compared, in which those parts are particularly affected; see (Ezekiel 23:21) , the Syriac version renders this and the former clause thus, "you shall shave your hair and cut off your breasts"; Kimchi thinks by the "breasts" are meant the oral and written laws, which ceased in the time of the captivity; but without any foundation.

For I have spoken it, says the Lord and therefore it shall be done.
