Jerome, on Gen 6:16

“Thou shalt make a window in the ark, and in a cubit shalt thou finish the top of it: and the door of the ark thou shalt set in the side: with lower, middle chambers, and third stories shalt thou make it.”

“(Verse 16.) Assembling, you shall make an ark, and you shall finish it with a cubit from above. As for the reason why it says, assembling, you shall make an ark, in Hebrew it has, 'you shall make the middle of the ark,' which Symmachus interpreted more clearly, saying 'transparent,' that is, making the ark clear, intending for a window to be understood.”
