The prophetess Anne will take great care of this flower of David and Aaron. Mary is a descendant of David through her father Joachim and of Aaron (brother of Moses) through her mother Anne. She is therefore of royal and priestly descent. Her priestly ancestry is deduced from her relationship with Elizabeth (Luke 1:5), and her royal race is deduced, in particular, from her marriage to Joseph "of the seed of David". Now, according to the Law of Moses, the orphaned heiress (Numbers 27:9) had to marry into the same clan (Numbers 36:8).
The times are coming to an end: Allusion to Daniel's prophecy about the seventy weeks (years) before the coming of the Messiah (cf. Daniel 9:22-27). This prophecy was widespread at the time of Christ.
The places reserved for virgins in the Temple are empty. The Messiah was to be a descendant of David (Isaiah 11:1f). He would be born of a virgin (Isaiah 7:13-14), but the belief that this virgin would have been educated in the Temple is not indicated. Anne-Catherine Emmerich mentions it in her Vie de la Vierge Marie (chapter 35): like Maria Valtorta, she attributes it to an unspecified tradition. It undoubtedly stems from the esteem in which the virgins of the Temple were held and the quality of their recruitment.
