This prayer, written for the Spanish and Portuguese Jews’ Congregation of London in the mid-19th century, is stated by the bar mitsvah prior to his ‘aliya blessing over the Torah. In the early 2010s, Rabbi Israel Elia ז״ל introduced the custom that a bat mitsvah recites a feminine form (with words marked in blue replaced by words marked in red) prior to her derasha. (In egalitarian communities where a bat mitsvah recieves an ‘aliyah as well, she may recite it prior to the ‘aliya blessing as well.)
