Adam Clarke on Jeremiah 15:4

I will cause them to be removed into an kingdoms of the earth - This seems to have respect to the succeeding state of the Jews in their different generations; and never was there a prophecy more literally fulfilled; and it is still a standing monument of Divine truth. Let infidelity cast its eyes on the scattered Jews whom it may meet with in every civilized nation of the world; and then let it deny the truth of this prophecy, if it can. The Jews are scattered through every nation, and yet are not a nation; nor do they form even a colony on any part of the face of the earth. Behold the truth and the justice of God!
