כָּ֥ל עַצְמוֹתַ֨י ׀ תֹּאמַרְנָה֮ יְהוָ֗ה מִ֥י כָ֫מ֥וֹךָ מַצִּ֣יל עָ֭נִי מֵחָזָ֣ק מִמֶּ֑נּוּ וְעָנִ֥י וְ֝אֶבְי֗וֹן מִגֹּזְלֽוֹ׃
Tous mes membres diront: "Seigneur, qui est comme toi?" Tu défends le pauvre contre un plus fort que lui, le malheureux et l’indigent contre leur spoliateur.
Kitzur Shulchan Arukh
If there is some excrement on the body, even if it is covered with clothing it is forbidden to speak about sacred things as it is said: "All my bones shall say, Hashem who is like You?"5Psalms 35:10. Therefore the entire body must be clean. Some authorities are lenient in this matter, but it is proper to follow the stricter opinion. If there is even the slightest bit of excrement on the edge of the anus, even if it is covered, according to all opinions it is of no avail, because in its original place it is more loathsome. In the case of one ill with hemorrhoids, see Magen Avroham 76: 8 who quotes from the Responsa of Radvaz, Volume III 315. The Magen Avraham concludes that such a person is not required to do anything [in order to pray.]6As long as there is no odor. This is true only if the hemorrhoids are external and without pus. If they are internal and there is constant seepage of internal, odorous matter, one must not pray or utter sacred words.
Mishneh Torah, Sabbath
We do not recite the blessing on the candle until one has benefited from its light, in order that he recognize [the difference] between the coin of this province and the coin of another province. And we may not recite a blessing over the candle of idolaters, as their standard parties (from which it is taken) are for idolatry. And we may not recite a blessing over a candle of idolatry, nor on a candle of the dead.
Shulchan Arukh, Orach Chayim
[Gloss: And we say the section of the daily offering. And there are those who say the order of the woodpile (Yoma 33a) and "Master of the World, You commanded us", etc. And if it is not possible to say with the congregation, one can say it in one's house and come back to read the section of the daily offering on one's own with the congregation [i.e. in its presence]. And the second time, one should intend it like reading in the Torah (Tur)] On Shabbat we say the verses of the additional offering of Shabbat instead of the section of the daily offering, but not on Rosh Chodesh or Yom Tov because we read the verses of the additional offering in the Torah. [Gloss: And there are those who also mention the additional offering of Rosh Chodesh - and so we practice in order to publicize that it is Rosh Chodesh, and so it is below in Siman 421 (Tur). And those who are exacting have practiced to shake at the time that we read the Torah as an illustration of the Torah that was given with trembling, and so too at the time that we pray, because of "all my bones will say to you, Lord who is like You?" (Abudarham)
