hannah wanted to get pregnant, so she went to the temple where Eli and his sons were at service. Not surprisingly, her wish was granted.
as was pointed out to me, Hanna did eventually have a natural son with her husband, who was not selectively infertile. I did not want to besmirch the bible character "Hanna" with her story similar to "Sarah's"
Are the wt writers suggesting, that the friends are to send their wives and daughters, sons into service, projects, the "Houses of God" knowing that, following the "things written beforehand " criminals* are lurking there?
* anybody disfellowshipped, put on "probation", reproof, is convicted of a crime, an offence against "divine" law.
