This adverb indicates origin or direction from another place. In Mark 1:38, Jesus tells his disciples to go ἀλλαχοῦ—to the neighboring towns—so he can preach there also. John 10:1 uses it metaphorically: anyone not entering the sheepfold by the door but climbing in ἀλλαχόθεν—another way—is a thief and robber. The classical usage emphasizes origin from a different source or location. Mark applies it literally to geographic movement, while John employs it figuratively for unauthorized access, contrasting the legitimate entrance (Christ as door) with illegitimate alternatives.
