No secular authority accepts 607 B.C.E., but we arrive at it solely because of the Bible which says the period of the Sabbaths that have to be paid back is 70 years.
Akekho umphathi wezwe owamukela u-607 BCE, kepha sifika kuwo kuphela ngenxa yeBhayibheli elithi inkathi yamaSabatha okumele ikhokhwe yiminyaka engama-70.
