A coat of skin (Genesis 3:21) signifies spiritual and natural good. (Arcana Coelestia 294)

A coat of various colors (Genesis 37:3) signifies appearances of truth where the spiritual of the natural principle is known. (Arcana Coelestia 4677, 4741)

A coat, as in Matthew 10:10, signifies the interior natural truth, or the truth of the natural principle.

The Lord's coat without seam, woven from above throughout (John 19:23), signifies the Lord's divine truth.

(Referencat: Exodus 27, 39, 39:27; Genesis 21; John 19)
