A Hebrew liquid measure, the tenth part of an homer (1 Kings 7:26, 38; Ezek. 45:10, 14). It contained 8 gallons 3 quarts of our measure. “Ten acres of vineyard shall yield one bath” (Isa. 5:10) denotes great unproductiveness.
Bath
A bath, in these verses, is a measure for liquids such as oil and wine, and has nothing to do with washing. Ezekiel 45:10 says, “Ye shall have just balances, and a just ephah, and a just bath,” and the next verse ties the bath to the ephah, which measures dry goods, so that both are the same size. Elsewhere the figure appears with awe: Solomon’s great bronze sea held “two thousand baths,” while Isaiah 5:10 warns of a vineyard of ten acres that yields only “one bath.” Ezekiel 45 is the clearest passage to read.
