Numbers 15:20

Of the first of your dough you shall present a loaf as a contribution ; like a contribution from the threshing floor , so shall you present it.

Present a loaf from the first of your ground meal and present it as an offering from the threshing floor.

Ye shall offer up a cake of the first of your dough for an heave offering : as ye do the heave offering of the threshingfloor, so shall ye heave it.
