145. In the Word too 'name' means the essential nature of a real thing, and 'seeing and calling by name' knowing characters, as in Isaiah,

I will give you the treasures of darkness and the hoarded riches of secret places, that you may know that it is I, Jehovah, the one calling you by name, the God of Israel. For the sake of My servant Jacob, and of Israel My chosen, and I have called you by name, I have surnamed you, but you do not know Me. Isaiah 45:3-4.

Here 'calling by name' and 'surnaming' mean knowing his character beforehand. In the same prophet,

You will be called by a new name which the mouth of Jehovah will declare. Isaiah 62:2.

This stands for his becoming a different person, as is clear from what precedes and what follows these words. In the same prophet,

O Israel, fear not, for I have redeemed you, I have called you by your name, you are Mine. Isaiah 43:1.

This stands for knowing character. Again in the same prophet,

Lift up your eyes on high and see; who created these? He who brings out their host by number; He will call them all by name. Isaiah 40:26.

This stands for His knowing them all. In Revelation,

You have a few names in Sardis, who have not soiled their garments. He who conquers will be clad in white garments and I will not blot his name out of the book of life; and I will confess his name before My Father and before His angels. Revelation 3:4-5.

Elsewhere in the same book,

Whose names have not been written in the book of life of the Lamb. Revelation 13:8.

In these places 'names' is in no way used to mean names but people's characters. Nor in heaven do they know anyone's name, only his character.

Dust, in Ezekiel 26:12, signifies the lowest things which are of the sensual principle of man. They can be either good or bad, depending on the context.

In Isaiah 40:12, the dust signifies exterior or natural truths and goods of heaven and the church.

In Genesis 2:7, the dust is good, and we see some interesting nuances:

First, there's this: 'To form the man, dust from the ground' is to form his external man, which had not previously been man... (Arcana Coelestia 94)

Here, this formation of our external body and mind is a precursor, setting the stage for God to "breathe into our nostrils".

In Arcana Coelestia 1610, we find this passage, where again, dust has a good signification:

'Dust of the earth' has regard to those things that are celestial, for, as shown already, 'the earth' means the celestial aspect of love; 'dust of the sea' has regard to those things that are spiritual, for 'the sea', as has also been shown, means the spiritual aspect of love; while 'as the stars of heaven' means both but in a higher degree. And because these things cannot be numbered they therefore became common expressions to describe growth and multiplication beyond measure.

Then, in Arcana Coelestia 3707, these ideas get pulled together:

The reason the dust of the earth symbolizes goodness is that the earth, [or land,] symbolizes the Lord’s kingdom and therefore goodness, as shown just above in §3705. The dust of that land, then, means goodness, but earthly goodness, since the land symbolizes what is lowest in the Lord’s kingdom....

But there are bad connotations, too. In Micah 7:14-17, licking dust symbolizes being only sensual - bodily and external, worldly, and selfish. It's much the same in Psalms 72:9, where "Barbarians will bow down before God, and His enemies lick the dust...". See Arcana Coelestia 249, 3413 for interesting explanations of this.
