10241. Their hands and their feet. That this signifies the interiors and exteriors of man, is evident from the signification of "hands," as being the interiors of man (of which below); and from the signification of "feet," as being the exteriors of man, thus his natural things, for these are exterior. (That the "feet" denote what is natural, thus the exteriors of man, see n. 2162, 3761, 3986, 4280, 4938-4952, 9406.) But that the "hands" denote the interiors is because the higher things of the body extend into the hands, and there terminate, consequently by the "hands" is signified whatever pertains to man, and also his power (see the places cited in n. 10019). But when both the "hands" and the "feet" are mentioned, then there is signified whatever is in the internal and also in the external man, or both spiritual and natural things. For this reason by "lifting up the hand" is signified power in the spiritual; and by "lifting up the foot," power in the natural (see n. 5327, 5328); moreover, by the extremes of man are signified all that pertains to him (n. 10044), and the extremes are the hands and feet. From all this it can be seen why Aaron and his sons were to wash the hands and feet when they entered into the Tent of meeting, or came near to the altar to minister.
