****Premise 3: Regarding Jeremiah 29:10,other modern translations, like the ESV, says, “When seventy years are completed for Babylon, I will visit you, and I will fulfill to you my promise and bring you back to this place."*****
There were 3 Visits to Jerusalem 1. Daniel and sundry were exiled in the first visit by Babylon 609/607 BC 2. The good figs namely Jechoniah and his brothers visit by Babylon approx. 597 BC 3. The bad figs were destroyed and WOULD NOT come back under Zedekiah when Jerusalem was destroyed approx. 586/587 BC **Jeremiah 29:10,other modern translations, like the ESV, says, “When seventy years are completed for Babylon, I will visit you, *** This was addressed to Daniel's group and the "GOOD FIGS" that were exiled under Jechoniah AS JERUSALEM AND ZEDEKIAH WAS NOT DESTROYED AT THAT TIME. ..... You will have to wait until Jeremiah 32:...in the TENTH year of Zedekiah which was the eighteenth year of Nebuchadnezzar that the word came for his and Jerusalem's destruction.
There was NO EXILE FOR Zedekiah and the BAD FIGS 1 The LORD showed me, and, behold, two baskets of figs were set before the temple of the LORD, after that Nebuchadrez'zar king of Babylon had carried away captive Jeconi'ah the son of Jehoi'akim king of Judah, and the princes of Judah, with the carpenters and smiths, from Jerusalem, and had brought them to Babylon. 2 Kgs. 24.12-16 · 2 Chr. 36.10 2 One basket had very good figs, even like the figs that are first ripe: and the other basket had very naughty figs, which could not be eaten, they were so bad. 3 Then said the LORD unto me, What seest thou, Jeremiah? And I said, Figs; the good figs, very good; and the evil, very evil, that cannot be eaten, they are so evil. 4 ¶ Again the word of the LORD came unto me, saying, 5 Thus saith the LORD, the God of Israel; Like these good figs, so will I acknowledge them that are carried away captive of Judah, whom I have sent out of this place into the land of the Chalde'ans for their good. 6 For I will set mine eyes upon them for good, and I will bring them again to this land: and I will build them, and not pull them down; and I will plant them, and not pluck them up. 7 And I will give them a heart to know me, that I am the LORD; and they shall be my people, and I will be their God: for they shall return unto me with their whole heart. 8 ¶ And as the evil figs, which cannot be eaten, they are so evil; surely thus saith the LORD, So will I give Zedeki'ah the king of Judah, and his princes, and the residue of Jerusalem, that remain in this land, and them that dwell in the land of Egypt: 9 and I will deliver them to be removed into all the kingdoms of the earth for their hurt, to be a reproach and a proverb, a taunt and a curse, in all places whither I shall drive them. 10 And I will send the sword, the famine, and the pestilence, among them, till they be consumed from off the land that I gave unto them and to their fathers. Even Matthew the gospel writer specified the exile occurred under Jechoniah. Matthew 1:11-12 So , Jehovah by means of Jeremiah @ chapter 29:10 was NOT talking about 70 years of exile from the time of Zedekiah and the destruction of Jerusalem. By your own calculations or should I say the WBTS, that would date Jechoniah's exile in 617 BC, 10 years before your 607 BC ...making ...80 years of exile .....617-537 = 80 years ...Totally wrong..... Scriptures show it was 70 years for Babylon...the org. got all its dates from the SDA and tweaked the dates like other scripture to their imminent down fall. All these dates are NOT important to most Christians as they accept The simple gospel of a changed life in Christ, but unfortunately the WBTS has made it their foundation and justification of their authority, if the dates are wrong, who selected them in 1874, 1914, 1919 or whatever date they currently use. Shalom.
