Job 5:20

In famine He will redeem you from death,
    and in war from the power of the sword.
Job 5:20 Modern English Version (MEV)
 
****************
 
In famine he shall redeem thee from death,.... In a time of extreme want of provisions, God so cares for his own dear people, that they shall not be starved to death by the famine; so in the famine in Egypt, which the Targum takes notice of, in the times of Abraham, and of Isaac, and of Jacob, and the patriarchs, there was food provided for them, so that they and their families were sustained, and perished not for lack of the necessaries of life: God sometimes goes out of his ordinary way, and works wonders for his poor and needy in distress, when they cry unto him; see Isa_41:17,
 
and in war from the power of the sword; or, "from the hands of the sword" (f): from swords in hand, when drawn, and men are ready to push with them with all their force; as he delivered and preserved Abraham from the sword of the four kings, when he waged war with them, Gen_14:20; and the Israelites, in the war of Amalek, in the times of Moses, Exo_17:8, which the Targum here refers to; and David from the harmful sword of Goliath, 1Sa_17:46, and others with whom he was concerned in war: and so the Lord covers the heads of his people in the day of battle oftentimes, when multitudes fall on their right hand and on their left.

Let’s recap, shall we? Job has lost his children, all his earthly possessions, and struck down with all sorts of physical maladies. This may not be the right time to be telling him how God saves his people from experiencing just these sorts of things.
