Saw a post about this so it reminded me of my question- we say that you say a Torah verse at the end of shemoneh esrei that begins with the first letter of your name and ends in the last letter of your name…what exactly is your name though? When it says to use the last letter of your name, is that the last letter of your last name or of your first name? Also is it our Aliyah name that we base it off of?
TLDR: my name is יעקב. Do I use yud and bet for my pasuk, or since I’m יעקב בן שמואל do I use yud and lamed. Or since my last name in Hebrew ends with a tzaddik, do I used yud and tzaddik?
