Isaiah 57:15 For thus saith the high and lofty One that inhabiteth eternity, whose name [is] Holy; I dwell in the high and holy [place], with him also [that is] of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones. 57:16 For I will not contend for ever, neither will I be always wroth: for the spirit should fail before Me, and the souls [which] I have made. 57:17 For the inequity of his covetousness was I wroth, and smote him: I hid Me, and was wroth, and he went on frowardly in the way of his heart. 57:18 I have seen his ways, and will heal him: I will lead him also, and restore comforts unto him and to his mourners.
