Seah

A seah (Hebrew se'ah) was a Hebrew dry measure equal to one-third of an ephah, approximately 7–8 liters (about 2 gallons). It was a common household measure for grain and flour. Abraham asked Sarah to make cakes from three seahs of fine flour for the angelic visitors (Gen. 18:6). Elisha prophesied that in Samaria, during the siege, a seah of fine flour would sell for a shekel (2 Kgs. 7:1, 16), a dramatic reduction from the famine price of a donkey's head for eighty pieces of silver. The seah also appears in the Mishnah and rabbinic literature as a standard unit for determining ritual obligations.
