פּירוש אויף בראשית 9:11

והקמתי AND I WILL ESTABLISH — I will give confirmation to my covenant; and in what consists this confirmation? “The sign of the rainbow”, as it goes on explaining at the end.

והקימותי את בריתי, “I shall maintain My covenant as applicable, etc.” The reason why G-d’s promise not to bring on another deluge is repeated in the same verse, is to underline that even if the human race would again be guilty of similar conduct to that which had brought about the deluge, this covenant would not be considered by G-d as null and void.

ולא יהיה עוד מבול לשחת הארץ, there will not ever again be the kind of catastrophe which will destroy the whole surface of the earth at the same time.
