Sword
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.

Ezekiel 38:8-13
8
After many days you shall be visited: in the latter years you shall come into the land that is brought back from the sword, that is gathered out of many peoples, on the mountains of Israel, which have been a continual waste; but it is brought forth out of the peoples, and they shall dwell securely, all of them.
9
You shall ascend, you shall come like a storm, you shall be like a cloud to cover the land, you, and all your hordes, and many peoples with you.
10
Thus says the Lord Yahweh: It shall happen in that day, that things shall come into your mind, and you shall devise an evil device:
11
and you shall say, I will go up to the land of unwalled villages; I will go to those who are at rest, who dwell securely, all of them dwelling without walls, and having neither bars nor gates;
12
to take the spoil and to take the prey; to turn your hand against the waste places that are [now] inhabited, and against the people who are gathered out of the nations, who have gotten livestock and goods, who dwell in the middle of the earth.
13
Sheba, and Dedan, and the merchants of Tarshish, with all the young lions of it, shall tell you, Have you come to take the spoil? have you assembled your company to take the prey? to carry away silver and gold, to take away livestock and goods, to take great spoil?
