Mouth
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.
Ezechiel 29:8-12
8
Proptera hæc dicit Dominus Deus : Ecce ego adducam super te gladium, et interficiam de te hominem et jumentum.
9
Et erit terra Ægypti in desertum et in solitudinem : et scient quia ego Dominus, pro eo quod dixeris : Fluvius meus est, et ego feci eum.
10
Idcirco ecce ego ad te, et ad flumina tua : daboque terram Ægypti in solitudines, gladio dissipatam, a turre Syenes usque ad terminos Æthiopiæ.
11
Non pertransibit eam pes hominis, neque pes jumenti gradietur in ea, et non habitabitur quadraginta annis.
12
Daboque terram Ægypti desertam in medio terrarum desertarum, et civitates ejus in medio urbium subversarum, et erunt desolatæ quadraginta annis : et dispergam Ægyptios in nationes, et ventilabo eos in terras.
