3421. 'And he called them names' means the essential nature of them. This is clear from the meaning of 'calling the names' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3237. And since calling the names or the name means the essential nature, the expression calling without the addition of 'the name' therefore means in the internal sense of the Word to be of some such particular nature, as in Isaiah,

Hear this, O house of Jacob, who are called by the name of Israel and who came out of the waters of Judah. For they are called after the city of holiness, and upon the God of Israel they place their reliance. Isaiah 48:1-2.

Here 'being called after the city of holiness' stands for being of some particular nature. And in Luke,

Behold, you will conceive in the womb and will bear a son, and you will call His name Jesus. He will be great and will be called Son of the Most High. Luke 1:31-32.

'Being called Son of the Most High' stands for His Essential Being (Esse).

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.
