Exodus 12:29
29. at midnight the Lord smote all the first-born in the land of Egypt—At the moment when the Israelites were observing the newly instituted feast in the singular manner described, the threatened calamity overtook the Egyptians. It is more easy to imagine than describe the confusion and terror of that people suddenly roused from sleep and enveloped in darkness—none could assist their neighbors when the groans of the dying and the wild shrieks of mourners were heard everywhere around. The hope of every family was destroyed at a stroke. This judgment, terrible though it was, evinced the equity of divine retribution. For eighty years the Egyptians had caused the male children of the Israelites to be cast into the river [Ex 1:16], and now all their own first-born fell under the stroke of the destroying angel. They were made, in the justice of God, to feel something of what they had made His people feel. Many a time have the hands of sinners made the snares in which they have themselves been entangled, and fallen into the pit which they have dug for the righteous [Pr 28:10]. "Verily there is a God that judgeth in the earth" [Ps 58:11].
Jonah 3:7
7. neither . . . beast . . . taste any thing—The brute creatures share in the evil effects of man's sin (Jon 4:11; Ro 8:20, 22); so they here according to Eastern custom, are made to share in man's outward indications of humiliation. "When the Persian general Masistias was slain, the horses and mules of the Persians were shorn, as well as themselves" [NEWCOME from PLUTARCH; also HERODOTUS, 9.24].
Jonah 4:11
11. that cannot discern between their right hand and their left—children under three of four years old (De 1:39). Six score thousand of these, allowing them to be a fifth of the whole, would give a total population of six hundred thousand.
much cattle—God cares even for the brute creatures, of which man takes little account. These in wonderful powers and in utility are far above the shrub which Jonah is so concerned about. Yet Jonah is reckless as to their destruction and that of innocent children. The abruptness of the close of the book is more strikingly suggestive than if the thought had been followed out in detail.
