John Calvin on Jeremiah 33:13

And in the next verse Jeremiah confirms the same thing, where he mentions, as before, the cities of the mountains, and the cities of the plains, and then the cities of the south, and adds also the land of Benjamin, which was a different part of the country, and he mentions generally the circuits of Jerusalem and the cities of Judah What then? The flocks, he says, shall pass under the hands of a numberer Here, again, is set forth a greater security, because shepherds would not, as it were, by stealth lead forth their sheep, and afterwards gather them in a hurry, as it is usually done, when there is any fear of danger. The sheep, he says, shall pass under the hands of a numberer This could not be the case but in time of perfect peace and quietness; for where there is fear, the shepherds can hardly dare send forth their flocks, and then they dare not number them, but shut them in; and they are also often compelled to drive their flocks into forests and desert places, in order to conceal them. When, therefore, Jeremiah mentions the numbering of them, he intimates that the whole country would be in a state of peace, as in other words, and without a figure, he presently will tell us. But the Prophet in this way exalted the benefits of God, and at the same time strengthened the minds of the weak, for as it has been said, this favor could have hardly been tasted by the Jews while in a state so despairing. The Prophet then made use of a homely and ordinary style when he spoke of flocks and herds. It now follows —

Jeremiah 33:14

14. Behold, the days come, saith the LORD, that I will perform that good thing which I have promised unto the house of Israel and to the house of Judah.

14. Ecce dies veniunt, dicit Jehova, et excitabo (vel, stabilium) sermonum meum benum, quem loquutus sum (vel, pronuntiavi) ad domum Israel et ad domum Jehudah.
