to go, travel, or move from one place to another
The word's basic force is straightforward physical movement: a person sets out, makes a journey, or goes to a destination. It covers the full range of travel, from a short errand (going to a neighbor's house at midnight) to a long journey across provinces. Because it is the ordinary Greek verb for going, it appears throughout the Gospels and Acts as a simple narrative word, and one common form of it often functions as a near-equivalent of "then", "having gone, he did X."
The word also carries, in a cluster of Johannine sayings, a distinctly solemn sense: Jesus announces that he is going away, to the Father, to prepare a place, to send the Paraclete. This departure language is not a different word, but the same verb of movement turned toward a unique destination. John uses it repeatedly to draw a contrast between Jesus coming from the Father and returning to him, and between his presence with the disciples and his absence that would be overcome by the Spirit. Acts 1:25 picks up the same idiom when it says Judas went to his own place.
