| Clarke's Commentary on the Bible Of all that was in the dry land - From this we may conclude that such animals only as could not live in the water were preserved in the ark.
Gill's Exposition of the Entire BibleAll in whose nostrils was the breath of life,.... Whether of fowls, beast, cattle, or creeping things: of all that was in the dry land, died; by which description fishes were excepted, since they breathe not, having no lungs, and are not on the dry land, where they cannot live, but in the waters. Some pretend it to be the opinion of some Jewish writers, that the fishes did die, the waters being made hot, and scalded them; but this fable I have not met with.
Geneva Study BibleAll in whose nostrils was the breath of life, of all that was in the dry land, died.
King James Translators' Notesthe breath...: Heb. the breath of the spirit of life
Matthew Henry's Concise Commentary7:21-24 All the men, women, and children, that were in the world, excepting those in the ark, died. We may easily imagine what terror seized them. Our Saviour tells us, that till the very day that the flood came, they were eating and drinking, Lu 17:26,27; they were deaf and blind to all Divine warnings. In this posture death surprised them. They were convinced of their folly when it was too late. We may suppose they tried all ways and means possible to save themselves, but all in vain. And those that are not found in Christ, the Ark, are certainly undone, undone for ever. Let us pause, and consider this tremendous judgment! Who can stand before the Lord when he is angry? The sin of sinners will be their ruin, first or last, if not repented of. The righteous God knows how to bring ruin upon the world of the ungodly, 2Pe 2:5. How tremendous will be the day of judgment and perdition of ungodly men! Happy they who are part of Christ's family, and safe with him as such; they may look forward without dismay, and rejoice that they shall triumph, when fire shall burn up the earth, and all that therein is. We are apt to suppose some favourable distinctions in our own case or character; but if we neglect, refuse, or abuse the salvation of Christ, we shall, notwithstanding such fancied advantages, be destroyed in the common ruin of an unbelieving world. |
