Jeremiah 33:26

Then will I cast away the seed of Jacob, and David my
servant
R. Jonah thinks that Jacob is put instead of Aaron, because of the two families of David and Aaron before mentioned; but in this latter part of the chapter no mention is made of priests at all; and by the "seed" is meant one and the same, the spiritual seed of Christ, the antitypical David, and servant of the Lord; and which are no other than the seed of Jacob, over whom the Messiah reigns; or the spiritual Israel of God, whether Jews or Gentiles, and whom the Lord never casts away, so as to perish; but they shall all be saved in the Lord with an everlasting salvation: (See Gill on Jeremiah 31:37); and even the seed of Jacob, and of David, who was of Jacob, in the line of Judah, shall not be in such sense rejected: [so] that I will not take [any] of his seed [to be] rulers over the
seed of Abraham, Isaac, and Jacob;
that is, any of the seed of David taken literally; from whom the Lord has taken one, or raised up one of his seed, even the Messiah, to be a ruler over all the spiritual seed of Abraham, Isaac, and Jacob; or of all that tread in their steps: but inasmuch as by the seed of Jacob and David may be meant the spiritual seed of Christ, by rulers taken from them may be intended spiritual rulers and governors of the church, or ministers of the Gospel: for I will cause their captivity to return, and have mercy on them;
not only their captivity from Babylon, and so the family of David restored and continued till the Messiah should spring out of it; but the spiritual captivity of the Israel of God, of which the other was a type, and would be brought about by the Messiah; who in his love and pity should redeem them, as he has, from sin, Satan, law, hell, and death.
