Noah the jeweler

Three simple questions about Noah's Ark: Did #Noah have more jewelry then "2 Chainz" and "Big Sean"? How did Noah tell the difference between day and night during the flood? did Noah's Ark have windows?

#Rabbi Johanan interpreted the words, "A light (צֹהַר, #tzohar) shall you make to the #Ark," in #Genesis 6:16 to teach that Gd instructed #Noah to set there in luminous precious stones and jewels, so that they might give light as bright as noon (צָּהֳרָיִם, #tzaharayim).Similarly, Rav Achava bar Zeira taught that when Noah entered the #Ark, he brought precious stones and jewels with him to keep track of day and night. When the #jewels shone dimly, he knew that it was daytime, and when they shone brightly, he knew that it was night. The #Gemara noted that it was important for Noah to be able to tell day from night, for some animals eat only during the day, and others east only during the night, and thus Noah could determine the proper feeding times for the animals under his care. The Gemara noted that if in Genesis 6:16 Gd told Noah, “A window shall you make to the ark,” then Noah should have been able to tell day from night. The Gemara explained that Noah needed the jewels because the account of Noah bringing jewels into the Ark followed the view that the celestial bodies – including the sun – did not serve during the year of the Flood. (Thus, no sunlight entered the Ark, and Genesis 6:16 must refer to jewels rather than a window)
