Genesis 6:13

I will destroy them with the earth - Not only the human race was to he destroyed, but all terrestrial animals, i.e. those which could not live in the waters. These must necessarily be destroyed when the whole surface of the earth was drowned. But destroying the earth may probably mean the alteration of its constitution. Dr. Woodward, in his natural history of the earth, has rendered it exceedingly probable that the whole terrestrial substance was amalgamated with the waters, after which the different materials of its composition settled in beds or strata according to their respective gravities. This theory, however, is disputed by others.

The directions concerning the ark embrace the purpose to destroy the race of man Genesis 6:13, the plan and specification of the ark Genesis 6:14-16, the announcement of the deluge Genesis 6:17, the arrangements for the preservation of Noah and his family, and certain kinds of animals Genesis 6:18-21.

Genesis 6:13

The end of all flesh. - The end may mean either the point to which it tends, or the extermination of the race. The latter is the simpler. All flesh is to be understood of the whole race, while yet it does not preclude the exception of Noah and his family. This teaches us to beware of applying an inflexible literality to such terms as all, when used in the sense of ordinary conversation. "Is come before me," is in the contemplation of my mind as an event soon to be realized. "For the land is filled with violence." The reason. "I will destroy them." The resolve. There is retribution here, for the words "corrupt" and "destroy" are the same in the original.

6:13 The end of all flesh is come before me; I will destroy them - The ruin of this wicked world is decreed; it is come, that is, it will come surely, and come quickly.
