I don't quite get what you are trying to expound upon here. My statement stands that there were no dedicated "temple virgins" who took life-long vows of celibacy.
In your first example of "women who waited at the door of the tabernacle", it wasn't exactly women held in high esteem, if you get my drift. In fact, Eli, the priest of the tabernacle, had some unbelieving sons who, needless to say, were quite a disappointment to him. In II Samuel 2:22 we read, "Now Eli was very old, and heard all that his sons did unto all Israel; and how they lay with the women that assembled [at] the door of the tabernacle of the congregation.", this tells me that they were hanging out at the outside of the door to the tabernacle waiting for whatever 'business' they could drum up, in other words, they were NOT doing anything that should be admired or emulated today. In Exodus 38:8, there is a description of items placed at the entrance to the tabernacle for the women who assembled at the door (a wash basin and a mirror), but I don't see any references of what their role was other than maybe just waiting there for their men to exit?
In the Judges story of Jephthah the Gileadite is a sad one. He had been thrown out of his father's house by his half-brothers because his mother was a prostitute. When the Israelites got into trouble with the neighbors later on, the people called upon him to lead them into battle. He had felt the presence of the Lord and his calling to lead the Israelites. He, like Gideon, wanted some kind of sign from the Lord that he would be sure of victory so he rashly made a vow that whoever came out his door to greet him after the victorious battle, he would offer up to the Lord. He never expected it would be his only child, a daughter, who had not been married yet (a virgin). He really found out how silly rash vows are but he fulfilled his promise anyway. He told his daughter what he had done and she accepted it. She asked for two months to travel with her friends to "bewail her virginity" which she did and then returned home. The Scripture says he did with her what he had promised though it did not go into detail about where he killed her, but he promised a burnt offering so that is what he did. The "custom" you are referring to is "That the daughters of Israel went yearly to lament the daughter of Jephthah the Gileadite four days in a year." (Judges 11:40)
Your next example about Anna, the Prophetess, is found in Luke 2:36-38 - "There was also a prophet, Anna, the daughter of Penuel, of the tribe of Asher. She was very old; she had lived with her husband seven years after her marriage, and then was a widow until she was eighty-four. She never left the temple but worshiped night and day, fasting and praying. Coming up to them at that very moment, she gave thanks to God and spoke about the child to all who were looking forward to the redemption of Jerusalem." So she was not a virgin, but a widow, who was obviously quite devoted to worship. This does still not confirm any form of a ritual celibate virgin who served in the Temple.
And, lastly, the Philo of Alexandria story was speaking about the Essenes. They were a small Jewish group that existed from around the second century B.C. to around the first century A.D. who congregated in communal life dedicated to asceticism, voluntary poverty, daily baptisms, and abstinence from worldly pleasures, including marriage. I don't think any scholar would even begin to equate them with the general practices of the Jewish people. With their ideas, it's easy to see why they died out.
So if you can come up with some more examples, I don't see any proof for the idea that Mary was some sort of "Temple virgin".
Excellant Boatbums....great to see this with the clarity you gave it.
My examples don't prove that, and I don't think that Mary was a temple virgin at the temple in Jerusalem. They show that the idea of women dedicated to God rather than to their husbands existed, if not in Saduccean Judaism then at its periphery, for example among the sects such as the Essenes. The best proof of that was in Mary's own words, "I know not man".
