John Wesley on Deuteronomy 26:12

The year of tithing - Heb. the year of that tithe, so called, either because these tithes were gathered only in that year. Or rather, because then only they were so bestowed; and whereas these second tithes for two years together were eaten only by the owners and Levites, and that in Jerusalem, in the third year they were eaten also by the strangers, fatherless, and widows, and that in their own dwellings.
