A 'sword,' as in Ezekiel 21:9-15, signifies a person so desolated that he can see nothing good and true, but only falsities and contradictions. A 'sword,' in the Word, signifies the truth of faith combating and the vastation of truth. In an opposite sense, it signifies falsity combating and the punishment of falsity.

The 'sword,' in Revelation 1:16, represents a dispersion of falsities by the Lord because the sword came out from His mouth, which means it comes from the Word. Because the Word is understood by doctrine taken from it, this is also symbolically meant. It is called a sharp two-edged sword because it pierces the heart and soul.

A 'flaming sword which turned every way,' as in Genesis 3:24, signifies divine truth in extremes, which, like the Word in its literal sense, can be turned.

1260. Since 'nations' in the Most Ancient Church and in the Ancient Church meant goods or good persons, therefore also in the contrary sense they mean evils or evil persons Similarly with 'peoples'; since these meant truths, therefore also in the contrary sense they mean falsities. For in a corrupted Church good is turned into evil, and truth into falsity, as a consequence of which the meaning of nations and peoples in that contrary sense occurs many times in the Word, as in Isaiah 13:4; 14:6; 18:2, 7; 30:28; 34:1-2; Ezekiel 20:13; and in many other places.
