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.

Matthew 13:24-30
24
He set another parable before them, saying, "The Kingdom of Heaven is like a man who sowed good seed in his field,
25
but while people slept, his enemy came and sowed darnel weeds also among the wheat, and went away.
26
But when the blade sprang up and brought forth fruit, then the darnel weeds appeared also.
27
The servants of the householder came and said to him, 'Sir, didn't you sow good seed in your field? Where did this darnel come from?'
28
"He said to them, 'An enemy has done this.' "The servants asked him, 'Do you want us to go and gather them up?'
29
"But he said, 'No, lest perhaps while you gather up the darnel weeds, you root up the wheat with them.
30
Let both grow together until the harvest, and in the harvest time I will tell the reapers, "First, gather up the darnel weeds, and bind them in bundles to burn them; but gather the wheat into my barn."'"
