'Hardeneth' in the Bible

A wicked man hardeneth his face; But as for the upright, he establisheth his ways.

Happy is the man that feareth alway; But he that hardeneth his heart shall fall into mischief.

He that being often reproved hardeneth his neck Shall suddenly be destroyed, and that without remedy.

So then he hath mercy on whom he will, and whom he will be hardeneth.
