And sometimes the infinitive comes without a pronoun - לבלתי עשות מחוקות התועבות (that you do not any of these abominable customs)²⁶², בהפך את הערים (when He overthrew the cities)²⁶³; therefore, whenever it comes with a pronoun, בעשותה אחת (in doing any of the things)²⁶⁴, בשבתך בביתך (when you sit in your house)²⁶⁵ – there will be a homiletical interpretation.

Leviticus 4:27 says,ואם נפש אחת תחטא בשגגה מעם הארץ בעשתה אחת ממצות יהוה אשר לא תעשינה ואשם(And if any one of the common people sin through error, in doing any of the things which the LORD has commanded not to be done, and be guilty). The infinitiveבעשתה*(in doing) has a pronoun in order to indicate that the verse is only talking about a person who sins on his own, not a person who sins on account of a Jewish court mistakenly telling him to sin²⁶⁶.*
