Arcana Coelestia # 9858
9858. 'With the work of a designer' means a product of the understanding. This is clear from the meaning of 'a designer' as the power of understanding, dealt with in 9598, 9688. The words 'a product of the understanding' are used because the Lord's spiritual kingdom, which is represented by Aaron's garments, is heaven's power of understanding, even as His celestial kingdom is its power of will. And the powers of understanding and will that a human being has correspond to those heavens, see 9835.
Luke 19:21-22

22
"He said to him, 'Out of your own mouth will I judge you, you wicked servant! You knew that I am an exacting man, taking up that which I didn't lay down, and reaping that which I didn't sow.
