Isaiah 33:15-16

He that walketh righteously... — The answer to the question shows that the words point not to endless punishments, but to the infinite holiness of God. The man who is true and just in all his dealings can dwell in closest fellowship with that holiness which is to others as a consuming fire. To him it is a protection and defence, a “rock fortress,” in which he can dwell securely, where he will find all that he needs for the sustenance of soul and body, the bread and the water of life. The picture of the righteous man is in part an echo, probably a conscious echo, of Psalms 15, 24
