To deliver their soul from death - To preserve their "lives," - for so the word "soul" is to be understood here. The meaning is, to keep them alive. That is, God is their Protector; He guards and defends them when in danger.
And to keep them alive in famine - In times of want. Compare Job 5:20. He can provide for them when the harvests fail. Famine was one of the evils to which the inhabitants of Palestine, and of Oriental countries generally, were particularly exposed, and it is often referred to in the Scriptures.

To deliver their soul from death - To watch over and protect them in all sudden dangers and emergencies, so that they shall not lose their Lives by any accident.
And to keep them alive in famine - Not only prevent sudden death by an instantaneous interposition of my power, but keep them from a lingering death, by extraordinary supplies granted them in an extraordinary manner; because I am all in all, and all everywhere.

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 Isaiah 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, Revelation 12:6.
