In John 2:6, 7, the water pots signify external knowledges; which may be filled with truths. They also signify all those features of the Word, and so of the Jewish church and its worship, which were signified and represented by Divine things in the Lord and from the Lord. (Apocalypse Explained 376[29])

3068. 'Let down now your pitcher' means submitting facts. This becomes clear from the meaning of 'letting down' as submitting, and from the meaning of 'a pitcher' as facts. The reason why a water-pot or a pitcher means facts is that 'water' means truth, 680, 739, 2702, and a pitcher is a vessel with water in it, even as factual knowledge is a vessel with truth in it. All factual knowledge is a vessel for truth, and all truth is a vessel for good. Factual knowledge without truth is an empty vessel, and so is truth without good; but factual knowledge in which truth is held is a vessel that is filled, as is truth in which good is held. Affection which is an attribute of love is what joins them together so that they may exist in order. For love is spiritual conjunction.
