Why should we reach out to the least of these ?
Our G-d, the G-d of Abraham, Isaac and Jacob, the G-d of Israel, said to Abraham: "I will bless those who bless you; And I will curse him who curses you;" (Gen. 12:3). He did this promise also to Isaac: "Cursed be everyone who curses you, and blessed be those who bless you" (Gen. 27:29). When Balak, king of the Moabites, the enemy of Israel, called Balaam to curse the people of Israel, he could only say what G-d ordered him to say: "Blessed is he that blesseth thee, and cursed is he that curseth thee" Israel ! (Num. 24:9)
Three times G-d the Father tells us: "Blessed is he who..... blesses Israel" !
