[WhatNot]

We know from Jer 25:11, 12 and 29:10-14, the desolation of Jerusalm would be fulfilled in seventy years. Daniel's own captivity ocurred in 605 B.C, It was now 538 B.C, some 67 years after the conquest. Daniel recognized the period of captivity was almost over.

Zechariah refers to the seventy year period as begining with the destruction of the temple,which took place in 586 B.C (Zech 7:5). The temple was rebuilt in 515 B.C (Ezra 6:15).

This is why I believe the seventy years has several beginings and endings.

Yes, but here you are speaking in literal terms, not symbolic.

If the 70 years is symbolic, not literal years, then there would be a symbolic, not literal, fulfillment.

The “roaming time frames” of Hebrew prophecies are well known. Joel 2:28 was fulfilled in Joel’s lifetime, in Acts 2nd chapter according to Peter, and yet remains to be fulfilled in the endtimes.
