Reference for Shabbat 23:12
ת"ר הנכנס לבקר את החולה אומר שבת היא מלזעוק ורפואה קרובה לבא ור"מ אומר יכולה היא שתרחם
Our Rabbis taught: One must not search [his garments] in the street out of decency. In like way R. Judah-others state, R. Nehemiah-said: One must not cause himself to vomit in the street, out of decency. <font>Our Rabbis taught: If one searches his garments [on the Sabbath] he may press [the vermin] and throw it away, providing that he does not kill it. Abba Saul said: He must take and throw it away, providing that he does not press it. R. Huna said, The <i>halachah</i> is, he may press and throw it away, and that is seemly, even on weekdays.</font> Rabbah killed them, and R. Shesheth killed them.<span class="x" onmousemove="('comment',' Even on the Sabbath (Rashi). ');"><sup>21</sup></span> Raba threw them into a basin of water. R.

Eleazar said: Vermin must not be killed on the Sabbath: this is the view of Beth Shammai; while Beth Hillel permit it. And R. Simeon b. Eleazar said likewise on the authority of R. Simeon b. Gamaliel: One must not negotiate for the betrothal of children [girls],<span class="x" onmousemove="('comment',' On marrying young v. T.A. II, pp, 28f.

The obligation of a child's education lies primarily upon his father (Kid. 30a), and was left to him originally, public instruction being given to adults only. By the reforms of R. Simeon b. Shetah and Joshua b. Gamala elementary schools were set up for children from the age of six or seven and upwards (J. Keth VIII, ad fin.). From this passage we may conclude that the system of engaging private teachers was also in vogue in the education of girls, v. Kid., Sonc. ed., p. 141, n. 1 and Ned., p. 107, n. 2. It may be observed that only boys are referred to here.

Our Rabbis taught: If one enters [a house] to visit a sick person [on the Sabbath], he should say, 'It is the Sabbath, when one must not cry out, and recovery will soon come.' R. Meir said, [One should say] 'It [the Sabbath] may have compassion.'<span class="x" onmousemove="('comment',' The due observance of the Sabbath will bring recovery in its wake.
