Job 31:22 KJV

Then let mine arm fall from my shoulder blade, and mine arm be broken from the bone.
Job 31:22, King James Version

In context

21 If I have lifted up my hand against the fatherless, when I saw my help in the gate:

22 Then let mine arm fall from my shoulder blade, and mine arm be broken from the bone.

23 For destruction from God was a terror to me, and by reason of his highness I could not endure.
