through all that time, when one came to a heap of twenty measures, there were but ten; when one came to the winevat to draw out fifty press-measures, there were but twenty;
Rashi on Haggai
so that they should not come to a heap of twenty measures So that you should not have a curse sent into your works as [there has been] until now; for they would set up a heap from which twenty seahs should be measured, and would find only ten.
Rashi on Haggai
when one would come to the wine vat That is the pit before the wine press, into which the wine flows.
Rashi on Haggai
to draw off fifty press-measures To draw out from [the winevat] fifty measures with which they would measure wine from the winepresses, and the name [of those fifty measures] is purah.
