Jeremiah 18:9 Meaning and Commentary

Jeremiah 18:9

And [at what] instant I shall speak concerning a nation, and
concerning a kingdom
By way of promise on the other hand: or, "and the moment I shall speak" as in ( Jeremiah 18:7 ) ; in favour to a people; signifying, that if they do that which is right and good, and continue therein, it may be expected that I will appear for and among such a nation and kingdom: to build and to plant [it];
to build up its fences that have been broken down, and to plant it with pleasant plants, and make it prosperous and flourishing, and protect and defend it, and keep it safe, and in a secure condition; so that it shall be in very thriving circumstances, and be out of the power of its enemies to hurt it.

Jeremiah 18:9 In-Context

7 The moment I speak concerning a nation, And concerning a kingdom, To pluck up and to break down, and to destroy,
8 And that nation hath turned from its evil, Because I have spoken against it, Then I have repented of the evil that I thought to do to it.
9 And the moment I speak concerning a nation, And concerning a kingdom, to build, and to plant,
10 And it hath done the evil thing in Mine eyes, So as not to hearken to My voice, Then I have repented of the good That I have spoken of doing to it.
11 And now, speak, I pray thee, unto men of Judah, And against inhabitants of Jerusalem, Saying: Thus said Jehovah: Lo, I am framing against you evil, And devising against you a device, Turn back, I pray you, each from his evil way And amen your ways and your doings.
