Aliya Summary: The torrential rains lasted for forty days and nights. The waters rose to great heights and covered even the highest mountains, killing all humans and animals; everything died aside for Noach and the other occupants of the teivah. After the waters raged on the earth another 150 days, G‑d caused the waters to subside. The teivah eventually rested on the Ararat Mountains, and shortly thereafter the mountain peaks came into view. Noach opened the window of the teivah and dispatched birds to see whether it was time to leave the teivah. First he sent a raven, which refused to execute its mission and just circled the ark. He then sent out a dove. On its second attempt the dove went and did not return, signaling that the earth was once again habitable. After one full year in the teivah, the earth had dried.
Commentators explain that G-d’s anger subsided and turned into mercy because of Noach’s prayers. Apparently, prayer has a soothing effect on G-d, something not overlooked by future traditions, but this could have been the seed and blueprint for the prayers that have evolved since.
