'Waters' particularly signify the spiritual parts of a person, or the intellectual aspects of faith, and also their opposites.

'The waters above the firmament,' as in Genesis 1:7, signify the knowledges in the internal self, and 'the waters beneath the firmament' signify the knowledges of the external self.

'Waters,' as in Ezekiel 47:9, refer to the New Jerusalem, and they signify spiritual things from a celestial origin.

'Many waters,' as in Revelation 17:1, signify truths of the Word adulterated. 'Waters' or 'rivers' signify spiritual, rational, or scientific things pertaining to truth.

'Waters … that go softly,' as in Isaiah 8:6-7, signify spiritual things, and 'waters … strong and many,' signify falsities.

'Waters,' as in Psalms 104:3, signify divine truths.

'Waters' signify truths in the natural self, and in the opposite sense, falsities.

'The waters were dried up from off the earth,' as in Genesis 8:7, signifies the apparent dissipation of falsities.

5657. 'That behold, each man's silver was in the mouth of his pouch' means that it was observed that the truths had been so to speak freely given. This is clear from the meaning of 'each man's silver in his sack' as truths freely given, dealt with in 5530, 5624, 'each man's silver in the mouth of his pouch' meaning much the same. The difference is that the latter statement means that the truths which were freely given were placed in the opening of the exterior natural; for 'the mouth of the pouch' means the opening of the exterior natural, 5497. The reason why so to speak freely is meant at this point is that they dwell in a state of uncertainty, unsure whether they want to be joined to the internal, for fear that they will cease to be of any worth. And when anyone dwells in a state of uncertainty he feels unsure about the truths that serve to corroborate.
