John 4:46
Once more he visited Cana in Galilee, where he had turned the water into wine. And there was a certain royal official whose son lay sick at Capernaum. — the return to Cana (site of the first sign, 2:1-11) creates structural parallelism. The royal official's son is sick at Capernaum (about 20 miles away), setting up the question of distance and faith.
