John Trapp on Nehemiah 7:3

Verſe 3. [non-Latin text not transcribed] Job 30.28. Till the Sun be hot] The Sun hath one of his names, in Hebrew, a calefaciendo, from heating, there is nothing hid from the heat thereof, Pſal. 19.6. The name here given to the Sun ſignifieth a miniſter, or ſervant: becauſe it is the common ſervant of the World, whereby God miniſtreth light, heat, and precious fruits to all people, Deut. 4.19. and 33.14. It whirleth about the World with incredible ſwiftneſſe; and is up in a morning before moſt people. Therefore till the Sun be riſen the Gates muſt be kept ſhut, to keep out the Enemy, who watcheth his opportunity.

And while they ſtand by] to ſee it done as it ought to be; leſt by the treachery or careleſneſſe of Under-officers, it ſhould either be undone, or ill-done.Etiam Tractate, Junius. Let them feel with their hands, (ſo ſome render it) whether the Gates are made faſt or not.

And appoint watches] Heb. Set thou watches. He ſpeaketh to the two Hanani's, and bids each of them, whoſe turn it was, ſee to the well-doing of it. Hoc tu facias, Cyropaed. Xenophon ſaith of Cyrus, that when he gave any thing in command, he never ſaid, Let ſome one do this, but do thou this.
