Interesting discussion. I'm not quite sure I follow. But if the third year of vassalship was when Daniel was deported, which was the 11th year of Jehoiakim, that means he was deported the same year as Jehoiachin and the other royal family members in year 8 of Nebuchadnezzar. It also means that Ezekiel and the deportation occurring in the 7th year of 3023 Jews. Year 11 of Jehoiakim is year 8 of Nebuchadnezzar. This is not consistent with the context of scripture which shows Daniel and the young children being deported first before any.
Interesting that the Bible didn't specify the third year of his being a "vassal" to Nebuchadnezzar or something as that so as not to confuse with his kingship. Sometimes the Bible for clarification will give two references for a year. In this case the "vassalship" is not only not mentioned at Daniel 1:1 but it actually says "kingship"...."In the third year of the KINGSHIP of Jehoiakim."
At verse 2 it mentions the second year of the "kingship" of Nebuchadnezzar. Maybe he was a vassal too under somebody?
This is just a mistake, desperate to make the scriptures work out, the WTS has directly contradicted what the Bible is saying and in so doing corrupted other details of scripture. That might be cause they did not think about the deportations in various years. Here is how it is laid out in the Bible when you use third year of kingship for Jehoiakim for the deportation of Daniel.
If year 11 of Jehoiakim is year 8 of Nebuchadnezzar, then there is a 3-year difference. 8+3=11. In that case the accession year of Nebuchadnezzar which is zero +3 would equal the third year of Jehoiakim. Thus Daniel would be deported during the accession year of Jehoiakim. This is the first deportation.
The second deportation of 3023 souls, including Ezekiel occurs near the end of year 7.
The third deportation in year 8 of more than 10,000 along with Jehoiachin occurs at the very end of year 8.
Then after a siege of Jerusalem in year 9 of Zedekiah, some were deported in year 18 before the city fell, probably some that surrendered, a total of 830 souls (Jeremiah 52:30)
Then of course, some were deported with Zedekiah after Jerusalem fell in year 19.
Some poor people were left in the land to work but ran down to Egypt and refused to return. These were deported by Nebuchadnezzar in his 3rd year upon returning to Judah (Jer. 44:14,28).
