Jeremia 23:4

When the Lord shall gather His people out of the dispersion, then will He raise up shepherds over them who will so feed them that they shall no longer need to fear or to be dismayed before enemies who might be strong enough to subjugate, slay, and carry them captive. The figurative expressions are founded on the idea that the sheep, when they are neglected by the shepherds, are torn and devoured by wild beasts; cf. Eze 34:8. They shall not be lacking; cf. for נפקד with this force, Sa1 25:7; in substance = not be lost. לא יפּקדוּ is chosen with a view to לא פקדתּם אתם (Jer 23:2): because the shepherds did not take charge of the sheep, therefore the sheep are scattered and lost. Hereafter this shall happen no more. The question as to how this promise is to be accomplished is answered by Jer 23:5 and Jer 23:6. The substance of these verses is indeed introduced by the phrase: behold, days come, as something new and important, but not as something not to happen till after the things foretold in Jer 23:4. According to Jeremiah's usage throughout, that phrase does not indicate any progress in time as compared with what precedes, but draws attention to the weightiness of what is to be announced. There is also a suggestion of "the contrast between the hope and the existing condition of affairs, which does not itself justify that hope. However gloomy the present is, yet there is a time coming" (Hgstb.). The promise: I make to arise (raise up) to David a righteous branch, rests upon the promise, Sa2 7:12; Ch1 17:12 : I raise up thy seed after thee, which shall be of thy sons-which the Lord will hereafter fulfil to David. Graf tries to show by many, but not tenable arguments, that צמח has here a collective force. That he is wrong, we may see from the passages Zac 3:8 and Zac 6:12,…

In this chapter the prophet, in God's name, is dealing his reproofs and threatenings, I. Among the careless princes, or pastors of the people (Jer 23:1, Jer 23:2), yet promising to take care of the flock, which they had been wanting in their duty to (Jer 23:3-8). II. Among the wicked prophets and priests, whose bad character is here given at large in divers instances, especially their imposing upon the people with their pretended inspirations, at which the prophet is astonished, and for which they must expect to be punished (v. 9-32). III. Among the profane people, who ridiculed God's prophets and bantered them (Jer 23:33-40). When all have thus corrupted their way they must all expect to be told faithfully of it.

23:4 Once the people were back in Judah (23:3), the Lord would appoint responsible shepherds. As good leaders, they would care for the people.
