John Lightfoot on John 2:7

[Jesus said, Fill, &c.] I. It is probable that the discourse betwixt Jesus and his mother was not public and before the whole company, but privately and betwixt themselves: which if we suppose, the words of the son towards the mother, "Woman, what have I to do with thee?" will not seem so harsh as we might apprehend them if spoken in the hearing of all the guests. And although the son did seem by his first answer to give a plain denial to what was propounded to him, yet perhaps by something which he afterward said to her, (though not expressed by the evangelist,) or some other token, the mother understood his mind so far, that when they came into company again she could intimate to them, "Whatsoever he saith unto you, do it."

II. He answered his mother, "Mine hour is not yet come": for it might be justly expected that the first miracle he would exert should be done in Jerusalem, the metropolis of that nation.
