And all thy estimation shall be according to the shekel of the sanctuary,.... The shekel kept in the sanctuary, which was the standard of all shekels; not that there was a shekel in the sanctuary different from the common one; for every shekel ought to have been as that, of the full weight and worth of it; and the estimation was to be according to such a shekel, and the money paid in such, even in full weight:twenty gerahs shall be the shekel; which the Targum of Jonathan calls "meahs" or "oboli", one of which was about three halfpence of our money, scarce so much, and weighed near eleven grains, as Bishop Cumberland has calculated: see Eze 45:12.
