9469. 'And fine linen' means the truth from this, that is to say, from the good which has a celestial origin. 'Flax' or 'linen' means truth, see 7601, and 'fine linen' means truth from the Divine, 5319; both kinds of truth exist in the natural man. 'Fine linen' means truth from a celestial origin because of its whiteness and softness.
Zechariah 3:3-5
3
Now Joshua was clothed with filthy garments, and was standing before the angel.
4
He answered and spoke to those who stood before him, saying, "Take the filthy garments off of him." To him he said, "Behold, I have caused your iniquity to pass from you, and I will clothe you with rich clothing."
5
I said, "Let them set a clean turban on his head." So they set a clean turban on his head, and clothed him; and the angel of Yahweh was standing by.
