ISA 35:8

8 And a maslul [(highway)] shall be there, and a derech [(road)], and it shall be called The Derech HaKodesh [(The Holy Road)]; the tameh [(unclean, impure person [see Isa 26:7])] shall not pass along it, inasmuch as it shall be for them, that is, the Holech Derech [(Walker of the Road, i.e., whoever is the [Redeemed] Wayfarer on the Derech HaKodesh)], even evilim [(morally bad foolish people)] shall not go astray thereon.
