The Sea of Galilee, which was also known as the Sea of Tiberias, is a large freshwater lake or "sea" in northern Palestine, about thirteen miles long and eight miles wide. It lies 690 feet below sea level. The Jordan River flows into it from the north and empties out of the lake's southern end. In New Testament times, Jesus resided for a time in Capernaum along the Sea of Galilee. Among his earliest disciples were fishermen whom he called from their work along the sea. Jesus taught along the Sea of Galilee and periodically crossed it during his ministry. The Gospels recount how he calmed a storm on the Sea of Galilee and walked upon its waters. After the resurrection, Jesus appeared to some of his disciples beside the sea (John 21:1-14).
