The seah (measure), Gen 18:6; Matt 13:33; Luke 13:21, one-third of an ephah, or twenty pints, was the ordinary measure for household purposes. , Ex 16:36; Lev 5:11; Num 5:15; Jud 6:19, etc. — ten omers, or three seahs, or sixty pints. The homer (heap), Isa 5:10, when used for dry measure, one hundred omers, or six hundred pints.
The Greek word translated "bushel," Matt 5:15, is supposed by some to answer to the Hebrew word seah. The Roman bushel was very nearly the same with the English peck. ) Liquid. — The log (basin). Measures of Capacity. Lev 14:10, six egg-shells full, one-tenth of a hin, or nearly one pint. , Ex 29:40; Ex 30:24; Num 15:4, etc. — one-sixth of a bath or ten pints.

The firkin, John 2:6, was a Greek measure, containing seven and a half gallons. III. Weights. " There were also the parts of a shekel, as the fourth, third, and half. The shekel, the maneh, and the talent were all originally names of weights. When the phrase "shekel of the sanctuary" is used, Ex 30:13, it means, not that this was different from the common shekel, but that it was a true standard weight, according to the authorized standard preserved in the sanctuary, or, as we should say, a sealed weight or measure, to denote that its accuracy is certified by authority.
To weigh substances the Jews had — The shekel, Am 8:5, half an ounce avoirdupois. The mineh or mina, Eze 45:12, one hundred shekels, or fifty ounces, equal to three pounds two ounces avoirdupois. The talent, 2 Sam 12:30, three thousand shekels, thirty maneh, fifteen hundred ounces, equal to ninety-three pounds twelve ounces avoirdupois.
