Question
Is this correct? The following are read in an undertone on Shabbat, none more?   Parshat Vayishlach (Genesis 32:4–36:43): The verse detailing the relations between Reuben and Bilhah (Genesis 35:22) is read in an undertone. Parshat Ki Tisa (Exodus 30:11–34:35): The verses describing the sin of the Golden Calf (Exodus 32:1-6) are often read in an undertone. Parshat Bechukotai (Leviticus 26:3–27:34): The verses containing the curses or admonitions (tochecha) (Leviticus 26:14-43) are traditionally read in an undertone and at a faster pace. Parshat Ki Tavo (Deuteronomy 26:1–29:8): Similar to Bechukotai, the section of curses (Deuteronomy 28:15-68) is also read in an undertone.  

Question
Is it sinful for one to live their life as a beggar, either off their family or the community, instead of working for a living, if one’s reason for doing so is not to spend their time learning Torah, but because they are lazy or dislike work or lack a work ethic?
