John Gill's Bible Commentary Ver. 3. And I said unto them, let not the gates of Jerusalem be opened until the sun be hot , etc.] Or until the heat of the day, or near noon; at least not till the sun had been up some time, and shone out clearly, and caused much heat; that if any enemies were near, or lying in wait, they might be discovered, and the inhabitants also up and ready to defend themselves: and while they stand by ; according to Aben Ezra, Hanani and Hananiah were to be present at the opening and shutting of the gates, and so Grotius; but these being the chief rulers, it is not likely; but rather those whom they appointed to look after them, these were to stand by while their servants did it; they were not to leave it wholly to them, but to see it done themselves: let them shut the doors, and bar them ; or “lay hold” on them, handle them to see whether they are shut fast or not: and appoint watches of the inhabitants of Jerusalem, everyone in his watch, and everyone to be over against his house ; no foreigners were to be of the watch, only inhabitants, and those everyone in their turn, and to be placed over against where they dwelt; and so it might be thought would be the more careful and diligent in their watch.
Matthew Henry Commentary
