John 2:6

Two or three measures, [1] called metreta. Both the Latin and Greek text, by the derivation, may signify a measure in general, according to the Rhemish translation: but metreta was a particular measure of liquids: yet, not corresponding to our firkins, I could not think it proper with the Protestant and M. N. to put two or three firkins. (Witham)
