John Gill Commentary 1 Samuel 25:11

"Shall I then take my bread, and my water, and my flesh that I have killed for my shearers, and give it unto men of whom I know not whence they are?" — 1 Samuel 25:11 (ASV)

Shall I then take my bread, and my water
Which include all food and liquors, everything eatable and drinkable; and "water" may be particularly mentioned, because very scarce in the wilderness, and so precious; though the Septuagint version has "wine" instead of "water":

and my flesh which I have killed for my shearers ;
whether oxen, or sheep, or lambs, as there might be of each sort, for an entertainment made on such an occasion:

and give [it] unto men whom I know not from where they are ?
which is another argument Abarbinel makes use of that he meant not David, but his men only, because he did not know who and from where they were.
