Ezekiel 45:10-12

They should also be fair in their commercial dealings. Their basic dry and liquid measures, an ephah (about one-half bushel) and a bath (about six gallons), were to be standard and equal. An ephah should always be a tenth of an homer (five to six bushels), and a bath should always be a tenth of an homer (five to six bushels). Likewise weights should be the same. One shekel (about two-fifths of an ounce) should equal 20 gerahs (about one-fiftieth of an ounce). Twenty shekels plus 25 shekels plus 15 shekels (60 shekels) should equal one mina (about one and one-quarter pounds). Different commentators and Bible dictionaries vary somewhat in explaining the modern equivalents of these amounts.

". . . linear measurements of the ancient Near East were not as accurate as those of today. This is also true of volume measurements. Ezekiel delineated the proper standard of volume measure in the terms of his day." [Note: Alexander, "Ezekiel," p. 982.]
