Matthew Poole and continuators on Leviticus 23:22

22 And when ye reap the harvest of your land thou shalt not make clean riddance of the corners of thy field, when thou reapest, neither shalt thou gather any gleanings of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the LORD your God.

From the plural, ye, he comes to the singular, thou, because he would press this duty upon every person who hath an harvest to reap, that none might plead exemption from it. And it is observable, that though the present business is onely concerning the Worship of God, yet he makes a kind of excursion to repeat a former Law of providing for the poor, to shew that our piety and devotion to God is little esteemed by him if it be not accompanied with acts of Charity to men.
