John Trapp on Jeremiah 17:19

Ver. 19. Go and ſtand in the gate of the children] The ſheep-gate ſay ſome: whereof ſee Neh. 3.1, 32. & 12.39. or, as others, the water-gate whereof Neh. 3.26. a place it was of great reſort and concourſe, and therefore fitteſt for this new Sermon to be made in; firſt, though afterwards alſo he was to preach it in all the gates of Jeruſalem, foraſmuch as it was about a matter of greateſt importance, even the ſerious ſanctification of the Sabbath-day: Diem ſeptimum Opifex mundi natalem ſibi ſacravit, & obſervari praecepit. That fourth Commandement ſaith Philo, is a famous precept, and profitable to excite to all kind of virtue and piety.
