884. 'And behold, in its mouth an olive leaf plucked off' means a small measure of the truth of faith; 'leaf' meaning truth, 'olive' good that stems from charity, 'plucked off' the fact that the truth of faith derives from that charity, and 'in its mouth' the fact that it was made visible. This is clear from the meaning of 'olive' and is evident from the very words themselves. That a tiny quantity is meant is clear from the fact that it was a leaf and no more.

In the Word, “light” in the highest sense represents Divine Truth: knowledge, ideas, understanding that come to us from the Lord. In lesser degrees -- the light of a lamp, the light of the moon and so forth -- it represents lower levels of truth, ideas and understanding drawn from more earthly sources. Also, the sun in the Word represents the Lord, with its heat representing the divine love and its light representing the divine wisdom. That wisdom flows into our minds and enters our lives in the form of truth -- things we can know and ponder that lead us and help us to be good people. This connection between light and thought is one of many spiritual/natural relationships that's embedded in our common language. People “see the light” when they understand something; we try to “shed some light” by bringing new thoughts to a difficult question; people are “enlightened” when they get new information or a more complete understanding of something. And a light bulb in a cartoon represents an idea!
