Reference for Sanhedrin 200:11
(משלי טו, טו) כל ימי עני רעים בן סירא אומר אף לילות בשפל גגים גגו ובמרום הרים כרמו ממטר גגים לגגו ומעפר כרמו לכרמים
Those who seduce to adultery are as the spark that kindles the ember. As a cage is full of birds, so are their houses full of deceit.<span class="x" onmousemove="('comment',' A quotation from Jer. V, 27 ');"><sup>21</sup></span> Restrain the multitude from entering into thine house, and bring not everyone thereinto. Let there be many to inquire after thy well-being, yet reveal thy secret to but one in a thousand. Guard the openings of thy mouth from her who lieth in thy bosom. Fret not over to-morrow's trouble, for thou knowest not what a day may bring forth,<span class="x" onmousemove="('comment',' Prov. XXVII, 1. ');"><sup>22</sup></span>
