To deliver their soul from death,.... Not a corporeal death, for the soul dies not, and is never in any danger of death; and should life, or the whole man, be intended here, yet those that fear the Lord, and hope in his mercy, are not exempted and secured from a corporeal death, but die as other men; though sometimes indeed they are remarkably preserved from death, and even in a time of general calamity; but a spiritual death is meant, which, while in a state of nature, they are under; but, being quickened at conversion, they live spiritually, and are preserved from dying any more in this sense; and also from an eternal death, which shall never harm them, nor have any power over them; and to keep them alive in famine; not corporeal, though the Lord does give meat to them that fear him, and sometimes in a miraculous way provides for them; as by sending ravens to feed them, and by increasing the cruse of oil; see Isa 41:17; but spiritual, a famine of hearing the word of the Lord; the Lord prepares a place for his church and people in the wilderness, where they are privately nourished with the word and ordinances, and their souls kept alive, Rev 12:6.
