Lukas 9:57-62

And as they were going baderech (on the road), a certain one said to Rebbe Melech HaMoshiach, I will follow you wherever you go. And Rebbe Melech HaMoshiach said to him, Foxes have dens, and the OPH HASHOMAYIM (birds of heaven) have nests, but the Bar Enosh does not have a place where he may lay down his head. And he said to another, Follow me. But the ish said, Adoni, allow me to go first and bury the Av of me. But Rebbe Melech HaMoshiach said to him, Leave the mesim (dead ones, spiritually unregenerate ones without hitkhadshut) to bury their mesim (dead ones), but you go and proclaim the Malchut HASHEM. And another said also, I will follow you, Adoni. But first allow me to say lhitraot to the ones in my bais. But Rebbe Melech HaMoshiach said to him, No one having put his hand upon the plow yet looking back to the things behind is fit for the Malchut HASHEM.
