Deferring to your preferred Protestant commentary (Gill died in 1771 and his chronology is not the consensus of scholars at all) is quite irrelevant, especially when it erroneously misconstrues the days for ‘Israel’s guilt’ with reigns of the house of Judah. (This is also cherry picking because Gill does not support jwposter’s bizarre revision of the entire neo-Babylonian period.)
Additionally, the Bible never once mentions ‘70 years of exile’, and it instead explicitly identifies Babylon’s 70 years as a period that ends when Babylon is called to account, not the subsequent return from exile.

Ezekiel's "alluding" to 390 years
The use of quotes around ‘alluding’ suggests he thinks he has a point. Back in reality, Ezekiel chapter 4 only actually states a period of “390 days”, which indeed alludes to a period of 390 years.
