'Tillage' in the Bible

Over those who did the work of the field for tillage of the ground was Ezri the son of Chelub:

and that we should bring the first fruits of our dough, and our wave offerings, and the fruit of all kinds of trees, the new wine and the oil, to the priests, to the rooms of the house of our God; and the tithes of our ground to the Levites; for they, the Levites, take the tithes in all the cities of our tillage.
