Adam Clarke on Isaiah 36:12

That they may eat their own dung "Destined to eat their own dung" - לאכל leechol, that they may eat, as our translation literally renders it. But the Syriac reads מאכל meechol, that they may not eat, perhaps rightly, and afterward ומשתות umishshethoth, or ושתות ushethoth, to the same purpose. Seventeen of Dr. Kennicott's MSS., ten of De Rossi's and two of my own, read מימי meymey, the water; mine have מימי שניהם meymey sheneyhem, and write in the margin מימי רגליהם meymey regaleyhem, the water of their feet, a modest way of expressing urine.
