10488. 'Put everyone his sword on [his] thigh' means truth springing from good engaged in conflict against falsity arising from evil. This is clear from the meaning of 'sword' as truth engaged in conflict against falsity, dealt with in 2799, 8294; and from the meaning of 'the thigh' as the good of love, dealt with in 3021, 4277, 4280, 5050-5062, 9961. The words 'sword on the thigh' are used because truth that is engaged in conflict against falsity and evil and is overcoming them must spring from good. All the power truth possesses is derived from it. Without good truth is not even truth, for it is no more than lifeless factual knowledge; consequently truth without good possesses no power at all. By truth springing from good a life in keeping with truth should be understood, for good is connected with life. From this it is evident why it says that the sword was to be put on the thigh, as also in David where what is said refers to the Lord,

Gird Your sword on Your thigh, O Hero, in Your glory and Your honour! Psalms 45:3.
