Exodus 10:28

And Pharaoh said unto him, Get thee from me, take heed to thyself, see my face no more; for in that day thou seest my face thou shalt die. Thus the tyrant flew into a rage; having lost, he gave way to his temper. That is the final state of obduracy, if sinners repudiate the messengers of God entirely and will not hear another word of God's truth.
