Ezekiel 45:12 - Matthew Poole's English Annotations on the Holy Bible

Having laid down the standard for weight and measure in less valuable things, and that are sold for money, now the standard is set down for the current coin which passed among them, and the valuation of which was part of the prince's prerogative. The first mentioned in the text is the shekel, which, saith the text, contained twenty gerahs; now every gerah was one penny halfpenny English value: the shekel then was two shillings and sixpence. The twenty shekels was two pounds ten shillings, the fifteen shekels was one pound seventeen shillings and sixpence, and twenty-five was three pounds two shillings and six pence. Maneh: some say it is one pound, and that the pound was either least, middle, or greatest, according as there were more or fewer shekels in it; the least or common pound was but seventeen shillings and sixpence; the next, which was the royal, was fifty shillings; and the greatest, or pound of the sanctuary, was sixty-two shillings and six pence.
