In most cases, "mouth" in the Bible represents thought and logic, especially the kind of active, concrete thought that is connected with speech. The reason for this is pretty obvious, but it also holds when people, for instance, remove a stone from the mouth of a well, which represents gaining access to spiritual ideas. The mouth is used for eating as well as speaking, of course. In those circumstances, it represents our first, most external perception of a new spiritual idea or desire. This also makes sense, mirroring the way tasting food in the mouth gives us an instant impression of the quality of the food.

6913. Verses 21-22 And I will give this people favour ¹ in the eyes of the Egyptians; and so it will be when you go, that you will not go empty-handed. And let a woman ask of her female neighbour, and of the female guest in her house, vessels of silver and vessels of gold, and clothes; and you shall put them on your sons and on your daughters. And you shall plunder the Egyptians.

'And I will give this people favour ¹ in the eyes of the Egyptians' means fear, on account of the plagues, which those steeped in falsities had of those belonging to the spiritual Church. 'And so it will be when you go, that you will not go empty-handed' means a life no longer destitute so far as the contents of the natural mind are concerned. 'And let a woman ask of her female neighbour, and of the female guest in her house' means that everyone's good will be enriched with such things as are suited to it. 'Vessels of silver' means factual knowledge of what is true. 'And vessels of gold' means factual knowledge of what is good. 'And clothes' means inferior factual knowledge corresponding to these. 'And you shall put them on your sons' means application to their truths. 'And on your daughters' means application to their forms of good. 'And you shall plunder the Egyptians' means that such things are to be taken away from those who are steeped in falsities and in evils arising from them.
