10228. 'To make expiation for your souls' means in order that evils may be removed. This is clear from the meaning of 'expiation being made for their souls' as being purified or delivered from evils by means of the truth of faith, dealt with above in 10218; and since purification or deliverance from evils is nothing other than the removal of them, this too is meant by the same words.

A person is not delivered from evils and consequently purified, but is withheld from them when he is maintained in good by the Lord; and in this way evils are removed, see the places referred to in 10057(end).

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.
