The destruction of Jerusalem in 587 B.C. was a monumental tragedy for Israel. The Babylonians finally breach the walls of Jerusalem and burn the Temole. King Zedekiah tries to flee, is captured, blinded and carried into captivity. Jeremiah describes the ravages of the siege in the Book of Lamentations. He is allowed to stay, but is taken away by some Jewish survivors in the opposite direction – to Egypt.
