John Trapp on Proverbs 30:19

Verſ. 19. And the way of a man with a maid] That is, either with a cloſe and chaſt virgin, that is kept cloſe from the acceſs of ſtrangers, and goes covered with a veyl; or elſe with a maid, that though defloured, yet would paſs for a pure virgin, and is ſo taken to be till her lewdneſs is diſcovered. It is expreſly noted of Rebecca to her commendation, that though fair to look upon, yet ſhee was a virgin, neither had any man known her, Gen. 24.16. there are that paſs for virgins, and yet it cannot be ſaid of them, that man never knew them.

The ſaurum cum virgo tuum vas fictile ſervet, Ʋt fugias quae ſunt noxia, tuta time.
