Ezra 6:14

They prospered through the prophesying of Haggai: this is a seasonable intimation that this great and unexpected success was not to be ascribed to chance, nor to the kindness or good humour of Darius; but unto God only, who by his prophets had required and encouraged them to proceed in the work, and by his mighty power disposed Darius's heart to such kind and noble purposes and actions. Artaxerxes; who is thought to be either,

1. Xerxes, Darius's son and successor, who is called also Artaxerxes, and Ahasuerus, who is here joined with his father Darius, possibly because he favoured the Jews, and promoted their cause with his father, and saw to the execution of his father's decree, and was his father's viceroy, if not made co-emperor with his father in his lifetime, which was not unusual. Or,

2. Artaxerxes Longimanus, the son of Xerxes, who was best known by the name of Artaxerxes; who is here joined with Cyrus and Darius, because though the temple was finished, as to the substance of the work, in Darius's reign, Ezra 6:15, yet it was afterwards more fully completed and adorned by Artaxerxes, as is evident from Ezra 7:20,27, by whom Nehemiah was sent to Jerusalem with a large commission and full power to take care about the building of the city, and all other things concerning the Jewish nation and religion.
