The edge of the sword in Genesis 34:26 signifies what is false and evil in a state of combat.

(Referencat: Arcana Coelestia 4501)

Finding, or being found, can have different meanings in the Word, depending on the context. Here are two examples:

From Arcana Coelestia 5756, 'Behold, the silver which we found in the mouth of our pouches' means when truth freely given.

In Revelation 18:21, we find this: "And one strong angel took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be cast down, and shall not be found any more." Here, "to not to be found any more," signifies not to rise again, according to Apocalypse Explained 1183.
