R. Nathan says: "money": to include money of (second-) tithe, (which, unlike first-tithe, reverts not to the Temple, but to the owner.) "vessels": to include any vessel. This tells me only of money and vessels. Whence do I derive (the same for) all things? From "to watch": to include any thing which requires watching.
