6 “There is no soundness in my flesh from the face of your anger.” But perhaps God is unjustly angry with you, O Adam; unjustly angry with you, O son of man; because now brought to acknowledge that your punishment, now that you are a man that has been placed in Christ's Body, you have said, “There is no soundness in my flesh from the face of Your anger.” Declare the justice of God's anger: lest you should seem to be excusing yourself, and accusing Him. Go on to tell whence the “anger” of the Lord proceeds. “There is no soundness in my flesh from the face of Your anger; neither is there any rest in my bones.” He repeats what he said before, “There is no soundness in my flesh;” for, “There is no rest in my bones,” is equivalent to this. He does not however repeat “from the face of Your anger;” but states the cause of the anger of God. “There is no rest in my bones from the face of my sins.”
