what date is traditionally given to the first deportation of exiles from judah into babylon
Jewish diaspora The first exile was the Assyrian exile, the expulsion from the Kingdom of Israel (Samaria) begun by Tiglath-Pileser III of Assyria in 733 BCE. This process was completed by Sargon II with the destruction of the kingdom in 722 BCE, concluding a three-year siege of Samaria begun by Shalmaneser V. The next experience of exile was the Babylonian captivity, in which portions of the population of the Kingdom of Judah were deported in 597 BCE and again in 586 BCE by the Neo-Babylonian Empire under the rule of Nebuchadnezzar II.
Nehemiah In the 20th year of Artaxerxes, king of Persia, (445/444 BC), Nehemiah was cup-bearer to the king.[5] Learning that the remnant of Jews in Judah were in distress and that the walls of Jerusalem were broken down, he asked the king for permission to return and rebuild the city.[6] Artaxerxes sent him to Judah as governor of the province with a mission to rebuild, letters explaining his support for the venture, and provision for timber from the king's forest.[7] Once there, Nehemiah defied the opposition of Judah's enemies on all sides—Samaritans, Ammonites, Arabs and Philistines—and rebuilt the walls within 52 days, from the Sheep Gate in the North, the Hananeel Tower at the North West corner, the Fish Gate in the West, the Furnaces Tower at the Temple Mount's South West corner, the Dung Gate in the South, the East Gate and the gate beneath the Golden Gate in the East.
