Proverbs 21:29 A wicked man hardeneth his face: but as for the upright, he directeth his way.
28:14 Happy is the man that feareth alway: but he that hardeneth his heart shall fall into mischief.
29:1 He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy.

Romans 9:18 Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
