Arcana Coelestia # 10626
10626. 'And he said, If now I have found grace in Your eyes, O Lord' means because such an outward form was accepted. This is clear from the representation of 'Moses' as the outward form that is receptive of what is inward, dealt with in 10607, 10614; and from the meaning of 'finding grace in Jehovah's eyes', when this refers to Moses, as his having been accepted because his character was such, so that the question of whether that outward form was accepted is meant, dealt with in 10563.
Skin
'Skins' or 'hides' signify external things, because the hide is the outermost organ of an animal where its interiors extend, the same as with a person's dermis or skin. 'Skin' corresponds to truth or to falsity in the extremes. See Arcana Coelestia 1835, 10036, and Apocalypse Explained 386. 'Skin,' as in Job 19:26, means the natural degree a person has with him after death.

In Job 19:20, this signifies being not entirely in falsities. (Apocalypse Explained 556[11])
