About 2 thousand years ago how was a new marriage registered among Hebrew people? Was it registered at all? How did a man and a woman officially become married? Was it just a kind of public announcement and a feast, after which it would be absolutely legal for them to start living together or did they have to somehow "authenticate" their marriage at the synagogue, perhaps, with the help of a priest?
(Please, note that this question is different from another question of mine on marriage that I asked 2 years ago)
