הֲרִאישׁ֣וֹן אָ֭דָם תִּוָּלֵ֑ד וְלִפְנֵ֖י גְבָע֣וֹת חוֹלָֽלְתָּ׃

Were you born before Adam Heb. הראישון. Were you born before Adam? This “hey” serves as the interrogative expression. Therefore, it is vowelized with a “hattaf pattah” and its meaning is: Were you born the first one, before Adam who was formed from the earth, so that you knew to fulfill all the wisdom of the commandments of the Creator?
