Before Jesus began his public ministry, he attended a wedding in Cana with his mother Mary and some of his disciples. During the wedding banquet, Jesus performed a miracle that involved changing water into wine. Cana is in Galilee, which is a region within the Biblical land of Israel. It is near Nazareth where Jesus spent much of his childhood.
John, the author of the Gospel of John in the New Testament of the Bible, indicates that this was the first miracle of Jesus, or at least the first that was witnessed by his disciples.
As explained in the Gospel of John, which is a part of the New Testament of the Bible:
"Woman, why do you involve me?" Jesus replied. "My hour has not yet come."
His mother said to the servants, "Do whatever he tells you."
Nearby stood six stone water jars, the kind used by the Jews for ceremonial washing, each holding from twenty to thirty gallons.
Jesus said to the servants, "Fill the jars with water"; so they filled them to the brim.
Then he told them, "Now draw some out and take it to the master of the banquet."
They did so, and the master of the banquet tasted the water that had been turned into wine. He did not realize where it had come from, though the servants who had drawn the water knew. Then he called the bridegroom aside and said, "Everyone brings out the choice wine first and then the cheaper wine after the guests have had too much to drink; but you have saved the best till now."
What Jesus did here in Cana of Galilee was the first of the signs through which he revealed his glory; and his disciples believed in him.
