And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and everything that is in the earth shall die. The announcement is very definite: I am bringing the deluge of waters upon (or over) the earth. That is the punishment which the Lord had had in mind all the while, and this is about to be realized in that universal flood. The result would be the destruction of all flesh in which is the breath of life, of all beings that breathe with lungs: all such beings would have to yield up their spirit.
