It may be asked how the blessed Virgin and St. Joseph could possibly have come so far without missing him; but we must take notice, that when the people went up to the temple from remote parts of Judea, the men went in one company, and the women in a separate company, whilst the children went in either company indifferently: so that St. Joseph imagined that he was with Mary, his mother, whilst she imagined he was with St. Joseph. (Nicholas of Lyra)
