Nehemiah 6:15

So the wall was finished in the twenty and fifth day of the month Elul, in fifty and two days.

The verse records the completion of the walls around Jerusalem by Nehemiah and his associates. The wall was finished in fifty-two days, less than two months after Nehemiah arrived, despite the plots of enemies. This happened during the reign of Artaxerxes Longimanus of Medo-Persia, about seventy years after the return of the first company of exiles under Zerubbabel and Joshua.

Artaxerxes is the king who issued the third and final decree for the restoration of Jerusalem in 457 B.C. While on the throne he saw the return of a company of Jews under Ezra, the finishing of the walls, the reorganization of the temple services, and great religious reformations instituted by Ezra and Nehemiah. During his long universal reign he often showed favor to God's people and recognized his trusted Jewish friends Ezra and Nehemiah as men appointed by God and raised up for a special work. The completed defenses showed that God had directed the work, and the surrounding enemies were left astonished and cast down.
