3. A type of the last and general overthrow of the world by fire and brimstone (2 Peter 3:6,7).
But here, as it simply respecteth the cause, which (as is afore related) was the sin that before you read of; so it precisely was a type of the last of these, and to that end put an end to the world that then was. The world that then was, being overflowed with water, perished, to signify, That the heavens and the earth which are now, are reserved unto fire, against the day of judgment, and perdition of ungodly men.
"I bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life from under heaven: and every thing that is in the earth shall die." By these latter words, as the cause, so the extension of this curse is expressed; and that under a threefold denotation.
1. Every thing that is in the earth.
2. All flesh wherein is the breath of life.
3. Every thing that is under heaven. So then, this deluge was universal, and extended itself not only to those parts of the world where Noah and that generation lived, which we find repeated before, but even over the face of all the earth; and it took hold of the life of every living thing that was either on all the earth, or in the air, excepting only those in the ark, as will the general judgment do: "And Noah only remained alive, and they that were with him in the ark" (Gen 7:23).
Ver. 18. "But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee."
"But with thee," &c. This concerns what was said before concerning the universality of the flood: As he also said above, "But Noah found grace in the eyes of the LORD." This Peter also notes, He "saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly" (1 Peter 2:5).
"With thee will I establish my covenant." My covenant of mercy, or my promise to save thee when I drown the whole world for their iniquity: And therefore he adds, "And thou shalt come into the ark."
"I will establish." Making and establishing of promises are not always the same: He made his promise to Abraham, he seconded it with an oath unto Isaac, and he confirmed, or established it to Jacob; for by him he multiplied the seed of Abraham as the stars of heaven for multitude (Psa 105:8-10).
