Beth Sarim
Jerusalem could not have fallen in either 586 or 587 BCE for such dates do not agree with the Bible and secular history. The date 607 BCE is the only date that fully accounts for the 70 years of Jeremiah as fully ex[plained over many decades by the celebrated WT scholars.
Carl Olaf Jonsson who wrote Gentile Times Reconsidered, the latest is the 4th edn., 2004 and fails to address fully the problem of the 70 years as a period of Exile-Servitude and Desolation and not just Babylonian supremacy or rulership and his date of 587 BCE conflicts with serious scholars who advocate 586 BCE.
