Therefore you shall say to them, When you have offered from it the best of it, then the rest shall be counted to the Levites as produce of the threshing floor , and as produce of the winepress .

“Say to the Levites: ‘When you present the best part, it will be reckoned to you as the product of the threshing floor or the winepress.

Therefore thou shalt say unto them, When ye have heaved the best thereof from it, then it shall be counted unto the Levites as the increase of the threshingfloor, and as the increase of the winepress.
