John Darby’s Synopsis
 Note, too, here, that it is not as with Israel in the wilderness that there was water from the smitten rock to drink. Here the promise is of a well of water springing up unto everlasting life in ourselves.
 It will be found in John's writings that, when responsibility is spoken of, God is the word used; when grace to us, the Father and the Son. When indeed it is goodness (God's character in Christ) towards the world, then God is spoken of.
