Genesis 8:22
כב) עֹד כָּל יְמֵי הָאָרֶץ זֶרַע וְקָצִיר וְקֹר וָחֹם וְקַיִץ וָחֹרֶף וְיוֹם וָלַיְלָה לֹא יִשְׁבֹּתוּ:
So long as the earth exists, seedtime and harvest, cold and heat, summer and winter, and day and night shall not cease." [translation by Judaica Press]

Suggested Discussion Questions:

Why do you think G-d made this promise? It was not at all clear that the earth would not become corrupt again.
