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.

In many cases, the spiritual meaning of "own," both as a verb and as an adjective, is relatively literal. When people are described as the "Lord's own," however, it specifically means those people who know Him and have His Word. This has taken various forms since the dawn of humanity; in the prehistoric church known as the "Most Ancient Church" the Lord's truth -- the direct expression of His love -- flowed into people directly. In the Ancient Church the Lord's Word was recognized in nature and in the form of deeply representative stories, some of which were passed on to us in the early chapters of Genesis. Among the Children of Israel the Lord's Word was expressed through the Ten Commandments, the laws of Moses, the very history of the nation of Israel and the various psalms and prophecies. The early Christians had those stories along with the teaching and inspiration of Jesus himself. We now have the whole Bible, including the teachings of Jesus, and can understand the Bible's true meaning. Each of these churches, then, was at some point the Lord's own.
