Jesus answers his mother, "Woman, what does that have to do with you and me? My hour has not yet come" (2:4). Was he turning her down?

Here is what John tells, in order. His mother said to him, "They have no wine" (2:3). "Jesus said to her, “Woman, what does that have to do with you and me? My hour has not yet come.”" (2:4). "His mother said to the servants, “Whatever he says to you, do it.”" (2:5). Then "Jesus said to them, “Fill the water pots with water.”" (2:7). John doesn't explain Jesus's words to her, or say what she expected him to do. In John's Gospel Jesus speaks to his mother twice, and both times he begins "Woman": here, and at the cross, "Woman, behold, your son!" (19:26). His hour comes up again: "no one laid a hand on him, because his hour had not yet come" (7:30), and "no one arrested him, because his hour had not yet come" (8:20). These notes add nothing from outside the text to the word Woman, and don't say what his answer meant beyond the words.
