What if one uses the same model used in the parable of the Good Samaritan ? To me, it is obvious, the Parable of the Sheep and Goats incorporates the second great commandment that Messiah taught, which is the pinnacle of Leviticus 19. The least of "these" includes the Jews and all those who do the will of our Father who art in heaven. And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleanings of thy harvest. And thou shalt not glean thy vineyard, neither shalt thou gather every grape of thy vineyard; thou shalt leave them for the poor and stranger: I am the LORD your God. Ye shall not steal, neither deal falsely, neither lie one to another. And ye shall not swear by my name falsely, neither shalt thou profane the name of thy God: I am the LORD. Thou shalt not defraud thy neighbour, neither rob him: the wages of him that is hired shall not abide with thee all night until the morning. Thou shalt not curse the deaf, nor put a stumblingblock before the blind, but shalt fear thy God: I am the LORD. Ye shall do no unrighteousness in judgment: thou shalt not respect the person of the poor, nor honour the person of the mighty: but in righteousness shalt thou judge thy neighbour. Thou shalt not go up and down as a talebearer among thy people: neither shalt thou stand against the blood of thy neighbour: I am the LORD. Thou shalt not hate thy brother in thine heart: thou shalt in any wise rebuke thy neighbour, and not suffer sin upon him. Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.
-- Leviticus 19, Catholic chapter nineteen, Protestant verses nine through eighteen
How was my question not civil? It was a clear reference, “least of my brethren”. If you think different, frame the question better, please.
