Ye shall offer up a cake of the first of your dough [for] an
heave offering
Of the first dough made of the first corn that was threshed, winnowed and ground, they were to make a cake, and offer it an heave offering unto the Lord; the quantity of it is not expressed, but was left to the people's generosity; no stinted measure was fixed by the law; but according to the Scribes, or the traditions of the elders, the quantity of the cake was the twenty fourth part of the first dough that was kneaded; not the forty fourth, as Buxtorf F16 through mistake says; so the Targum of Jonathan,
``of the first of your dough, one out of twenty four (i.e. the twenty fourth part of it), ye shall separate a separation for the priests,''with which agrees the Misnah F17, though according to that, if made to sell publicly it was the forty eighth part of it. Some, because ( Numbers 15:21 ) begins and ends with (m) , "mem", which numerically signifies "forty", think this is an instruction to a bountiful person to give the fortieth part F18:
as [ye do] the heave offering of the threshing floor, so shall ye
heave it;
as the two wave loaves and firstfruits of their harvest, ( Leviticus 23:16 Leviticus 23:17 ) .
