Jamieson, Fausset & Brown, on Gen 6:17

“Behold I will bring the waters of a great flood upon the earth, to destroy all flesh, wherein is the breath of life, under heaven. All things that are in the earth shall be consumed.”

“And, behold, I, even I, do bring a flood--The repetition of the announcement was to establish its certainty (Gen 41:32). Whatever opinion may be entertained as to the operation of natural laws and agencies in the deluge, it was brought on the world by God as a punishment for the enormous wickedness of its inhabitants.”
