The Skin of my Teeth

“The skin of my teeth” in a new light, Job 19:20

Tynd My bone hangeth to my skin, and my flesh is away, only there is left me the skin about my teeth.
ASV My bone cleaveth to my skin and to my flesh, and I am escaped with the skin of my teeth.
DRA My bone hath cleaved to my skin, and nothing but lips are left about my teeth.
YLT To my skin and to my flesh Cleaved hath my bone, And I deliver myself with the skin of my teeth.
LXX: ἐν δέρματί μου ἐσάπησαν αἱ σάρκες μου, τὰ δὲ ὀστᾶ μου ἐν ὀδοῦσιν ἔχεται.
The flesh under my skin has rotted, and my bones are carried in my teeth.

I get a picture of Job’s muscles being gone, and he barely saves himself, by holding his bones in his teeth.
