Pitch Within and Without and the Dimensions of Noah's Ark

"And you shall cover it inside and out with pitch" (Genesis 6:14). Elsewhere it says [of Moses' basket], "And she daubed it with bitumen and with pitch" (Exodus 2:3). The difference: there, because the waters were gentle, "she daubed it with bitumen and with pitch" - bitumen because of the smell and pitch because of the water. "And this is how you shall make it" (Genesis 6:15). This one [ark] and that one [the Temple] - one was destined to be measured by your cubit. This is what is written, "The length, in cubits by the first measure, was sixty cubits, and the breadth twenty cubits" (2 Chronicles 3:3). And why does one call them tevikin? Because they would store [grain] in them. And the Rabbis say: after the name of Noah's ark [tevah]. "Three hundred cubits the length of the ark" (Genesis 6:15). Bar Hunya said: "I will meditate on Your precepts; I will delight in Your statutes" (Psalms 119:15-16) - the Torah taught you proper conduct, that if one makes a ship to stand in the harbor, he should make its breadth one-sixth of its length and its height one-tenth of its length. "And this is how you shall make it" - with His finger the Holy One, blessed be He, showed Noah: like this and like this you shall make it. And before the days of the flood came, the unclean creatures were more numerous than the clean. The Holy One, blessed be He, commanded to increase the clean and reduce the unclean, and said to him, "Of every clean animal" and so forth (Genesis 7:2).
