I might think, even water and salt; it is, therefore, written "of herd, flock, wine, and strong drink." Just as these are one fruit from another, originating from the earth [(Animals, too, derive their sustenance from the earth)], so, only all of this nature (is purchasable with tithe money).
"of the herd": We re hereby taught that a cow is acquired (for tithe money) together with its skin (i.e., the skin need not be sold for something which can be eaten.)
"of wine": the jug, together with its (storage vessel).
