И Сим и Иафет взяли одежду и положили ее на оба плеча, и пошли назад, и покрыли наготу отца своего; и их лица были отсталыми, и они не видели своего отца'нагота
Berakhot
Rab Judah said : It is forbidden to read the Shema' in the presence of a naked gentile. Why is a gentile specified ? Even by a naked Israelite it is likewise [forbidden] ! [That it is forbidden with an Israelite is obvious] ; but it was necessary to specify the case of a gentile. For thou mightest have said : Since it is written with reference to the gentiles, "Whose flesh is as the flesh of asses" (Ezek. xxiii. 20), argue that [in this matter the naked gentile is to be considered] only like an ass ; therefore he informs us that to them also [when exposed] is "nakedness" attributed ; for it is written, "And they saw not their father's nakedness" (Gen. ix. 23).
Sanhedrin
R. Amram, the son of R. Simon b. Abba, said: "What does the passage (Ib., ib. 26, 30) Who hath woe? Who hath sorrow? Who hath quarrels? Who hath complaints? Who hath wounds without cause? Who hath redness of eyes? They that tarry late over the wine; they that become sick for mixed drink, mean? When R. Dimi came from Israel, he said : "It was said in the West that he who tries to explain the passage above from the beginning to the end is correct, and he who tries to explain it from the end to the beginning is also correct.
Shabbat
I'll say that is indeed so [that one can say the Shema because of the verse in Ezekiel]! ... [Why do we dismiss it?] Scripture says,... "They did not see the nakedness of their father" [Genesis 9:23]. [This verse refers to Noah, a gentile.]
