Saying a Half Pasuk
This is the approved revision of this page, as well as being the most recent.
- In general it is forbidden to say half a pasuk.
- For this reason if a person learns a whole pasuk while learning he should say Hashem's name as it is read when he's reading the Torah so as not to break up the pasuk.
- It is permitted to say the 13 middot harachamim and conclude with the words v'nakeh since one's intent is as a request from Hashem and not in a way of reading pesukim, even if it is said by an individual.
