Halakhah sobre Cantares 2:14

(Lamed) According to our approach, this is the intention of the statement of [the Sages] may their memory be blessed, in Avot, “Do not be evil in front of yourself (bifnei atsmecha)” – the explanation of which is in your essence. As we are holy seed and we will not change in essence. And all of the sins of the Children of Israel are only their appearance, which will not be permanent, but only present from time to time. And that which they said, “But even if the whole world tells you that you are righteous, you should be like an evildoer in your eyes” – the explanation of [“in your eyes”] is in your appearance. [This is] like “and its appearance (literally, eye) was like the appearance of bdellium” (Num. 11:7) – the explanation of which is the appearance, and that is the description. And so you should increase courage, have much soap, whiten your clothes and fulfill the desire of your Creator who says, “Show me your appearance.”⁸⁵This literary allusion is also from Song of Songs (Shir HaShirim 2:14). And behold anything that is not in the essence is only in the appearance. And [that] which is in the appearance is only incidental, and that which is incidental will not be permanent. Therefore [with] the seed of Avraham, even if their hands are charred, the blackness will not be permanent; and they will necessarily be whitened and return to their beauty and their essence. Rather [it is] their good deeds [which] are their essence. And [so] behold, something impermanent is called deception (khazav), as in (Isaiah 58:11), “whose waters do not fail (yekhazvu).” And this is the intention of the midrash that said, “the deceptions and vanities that Israel does are worthwhile.” [It] means all of the sins – [both] light and severe – are only deception, since they are incidental. As their essence is pure and clean, like Avraham their bequeather, and as mentioned. And this is the intention of the statement of [the Sages], may their memory be blessed, in Chapter 1 of Tractate Rosh Hashanah⁸⁶Rosh Hashanah 17b., “Ilfa brought up [a contradiction]: It is written [about God], ‘and abundant in kindness’ (Exod. 34:6); and [yet in the same verse], it is written ‘and truth.’  He answered, ‘Initially [He judges in] truth, but in the end, abundant in kindness.’” And also there (Rosh Hashanah 17a), “Beit Hillel say, ‘[He who is] abundant in kindness inclines towards kindness.’” [This is] meaning [that] since the good deeds are essential, they are lasting and they are [therefore] true; but the sins are deception. And just like ‘a little bit of light pushes off much of the darkness,’ so does a little bit of truth push off much deception. And therefore He inclines towards kindness, because of the truth.

The Gemara, Berakhot 24a, declares, "A woman's voice is provocative, as it says, 'For sweet is your voice and your countenance is comely' " (Song of Songs 2:14). Recognition of the sexually provocative quality of the female voice leads to halakhic ramifications which are two-fold in nature. Since the female voice may arouse sexual desire, halakhic considerations of feminine modesty dictate that a woman should not sing in the company of men. By the same token, a man may not listen to the voice of a female vocalist (Even ha-Ezer 21: 1). Moreover, since the female voice is described as "ervah" or "nakedness," a male may not read the shema, study Torah or recite a blessing when the song of a woman, even of his own wife, is audible to him, just as he may not engage in these activities in the presence of naked or exposed portions of the female body (Oraḥ Hayyim 76:3).
