{A cup} (pot(8872)ion). Probably the ordinary wine of the
country mixed with two-thirds water, though the word for wine
(oinos) is not used here in the Gospels, but "the fruit of the
vine" (ek tou gen(886d)atos t(8873) ampelou). See  Mt 26:26-29  for
discussion of important details. Mark and Matthew give
substantially the same account of the institution of the Supper
by Jesus, while  Lu 22:17-20  agrees closely with  1Co 11:23-26 
where Paul claims to have obtained his account by direct
revelation from the Lord Jesus.
