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 gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God. (Leviticus 23:22)
This verse repeats the instruction of ch. 19:9, 10. It seems fitting that special attention should be called to the poor and the stranger at a time when there was plenty for all—harvesttime.
