Charles Ellicott Commentary Leviticus 11:34

"All food [therein] which may be eaten, that on which water cometh, shall be unclean; and all drink that may be drunk in every [such] vessel shall be unclean." — Leviticus 11:34 (ASV)

That on which such water cometh. —Better, upon which water cometh, that is, all food which is prepared with water for eating becomes defiled when the carcass of such an unclean reptile falls on it.

The same is the case with any beverage which is drunk from any kind of vessel; if the said carcass falls into it, it is rendered unclean.

According, however, to the canons that prevailed during the Second Temple period, the meaning of the first part of this verse is that items constituting human food become defiled by the carcass in question only when any water whatsoever has been poured upon them, even if these food items have afterwards become dry. But if they have not been moistened, they do not become defiled.

By "water," these authorities understand any of the following seven liquids:

• Water
• Dew
• Oil
• Wine
• Milk
• Blood
• Honey
