BSB(i)
10 You must use honest scales, a just ephah, and a just bath.
11 The ephah and the bath shall be the same quantity so that the bath will contain a tenth of a homer, and the ephah a tenth of a homer; the homer will be the standard measure for both.
12 The shekel will consist of twenty gerahs. Twenty shekels plus twenty-five shekels plus fifteen shekels will equal one mina.
