1165. In the Word 'Mizraim' or Egypt means knowledge, that is, various facts, by which people wish to probe into the arcana of faith and so confirm the false assumptions acquired in that way. 'Mizraim' also means simply knowledge, and so knowledge that is useful. This is clear not only from the places just quoted but also from very many others which would fill up page after page if they were all included. See Isaiah 19:1-end; Isaiah 30:1-3; 31:1-3; Jeremiah 2:18, 36; Jeremiah 42:14-end; Jeremiah 46:1-end; Ezekiel 16:26; 23:3; Ezekiel 29:1-end; Ezekiel 30:1-end; Hosea 7:11; 9:3, 6; 11:1, 5, 11; Micah 7:12 [NCBS: 7:15]; Zechariah 10:10-11; Psalms 80:8 and following verses.

3413. 'And filled them up with dust' means by means of earthly things, that is, by means of self-love and love of material gain. This is clear from the meaning of 'dust' as such, dealt with in 249. The meaning is that those who are called 'the Philistines', that is, who are not concerned with life but with doctrine, efface interior truths by means of earthly loves, which are self-love and love of gain. Because of those loves they are called 'the uncircumcised', 2039, 2049, 2056, 2632. Indeed people who are under the influence of those loves cannot avoid 'filling up the wells of Abraham with dust', that is, effacing the interior truths of the Word by means of earthly things, for there is no way in which they are able from these loves to see spiritual things, that is, things which belong to the light of truth from the Lord. In fact those loves introduce darkness, and this banishes that light, for as stated just above in 3412, as the light of truth from the Lord draws nearer, people who are concerned with doctrine alone and not with life are plunged into complete darkness and stupidity. Indeed they become like those in a rage, doing all they can to destroy truths in every way. For self-love and the love of gain are such that they do not allow any truth at all from the Divine to come anywhere near them. Nevertheless those people are able to boast of and pride themselves in the fact that they know truths; indeed they proclaim them with seeming zeal. It is however the fires of self-love and love of gain which inflame them and spur them on, and their zeal is merely the enthusiasm fired by those loves. This becomes quite clear from the fact that even though truths run counter to such persons' actual lives they are able to proclaim them with the selfsame zeal or enthusiasm. These are the earthly things which block the Word itself, the fountain of all truth.
