Please see Yeshayahu 43:14 with Targum Yonasan and Rashi.
- Is it saying that the Jews went to Bavel in ships? If so, do we find this elsewhere in Tenach or other evidence of it?
- If they didn’t use ships, how did the Jews get to Bavel?
- According to the Targum and Rashi yes. Personally, I am not aware of other places that it is mentioned.
- There certainly were Jews that got to Bavel in other ways besides ships, namely by foot. As the Midrash says Yalkut Shemoni (Tehillim 137-1) that Nevedhadnezzar didn’t allow the Jews to sit or rest until they passed the Euphrates river, so that they wouldn’t have a chance to daven, and only after they crossed into Bavel did he let them sit down.
