Artaxerxes, Artaxerxes'

Facts:

Artaxerxes was a king who reigned over the Persian empire from about 464 to 424 BC.

During Artaxerxes' reign, the Israelites from Judah were in exile in Babylon, which was under the control of Persia at that time.
Artaxerxes allowed Ezra the priest and other Jewish leaders to leave Babylon and go back to Jerusalem to teach the Israelites the Law of God.
Later during this time, Artaxerxes also allowed his cupbearer Nehemiah to return to Jerusalem to lead the Jews in rebuilding the walls surrounding the city.
Because Babylon was under the rule of Persia, Artaxerxes was sometimes called the "king of Babylon."
Note that Artaxerxes is not the same person as Ahasuerus (Xerxes).
