I have heard the check of my reproach, and the spirit of my understanding causeth me to answer.
Check of my reproach - i:e., the castigation intended as a reproach (literally, shame) to me (Job 19:29).
And - rather, 'but.'
Spirit of ... understanding - literally, 'the spirit from my understanding:' my rational spirit; answering to 'calm thoughts' (Job 20:2). In spite of thy reproach, urging me to 'hastiness,' I will answer in calm reason.
