The joyous scene portrayed in these verses starkly contrasts the taunts of Sanballat and Tobiah recorded in Chapter 4. These two men were determined to undermine Nehemiah’s efforts to rebuild the walls, even resorting to biting sarcasm to demoralize the workers.

“What does this bunch of poor, feeble Jews think they’re doing? Do they think they can build the wall in a single day by just offering a few sacrifices? Do they actually think they can make something of stones from a rubbish heap—and charred ones at that?” – Nehemiah 4:2 NLT

Not to be outdone by his friend Sanballat, Tobiah added, “That stone wall would collapse if even a fox walked along the top of it!” (Nehemiah 4:3 NLT).

But both men were proven wrong. Not only had the wall been built, but it was sturdy enough to carry the weight of two choirs and a host of joyous celebrants who gathered for its dedication. Despite opposition and setbacks, the work had been completed and the day had come to thank God for making it all possible. This elaborate and meticulously staged ceremony was nothing less than a worship service designed to express gratitude to Yahweh for His goodness and greatness. He had kept His promise to return the people of Judah to their land and had divinely orchestrated the rebuilding of the city, its walls, and the Temple.

Years earlier, when the people were still reconstructing the Temple, God sent a message of hope through His prophet Zechariah.

“This is what the Lord of Heaven’s Armies says: My love for Mount Zion is passionate and strong; I am consumed with passion for Jerusalem!

“And now the Lord says: I am returning to Mount Zion, and I will live in Jerusalem. Then Jerusalem will be called the Faithful City; the mountain of the Lord of Heaven’s Armies will be called the Holy Mountain.

“This is what the Lord of Heaven’s Armies says: Once again old men and women will walk Jerusalem’s streets with their canes and will sit together in the city squares. And the streets of the city will be filled with boys and girls at play.

“This is what the Lord of Heaven’s Armies says: All this may seem impossible to you now, a small remnant of God’s people. But is it impossible for me? says the Lord of Heaven’s Armies.

“This is what the Lord of Heaven’s Armies says: You can be sure that I will rescue my people from the east and from the west. I will bring them home again to live safely in Jerusalem. They will be my people, and I will be faithful and just toward them as their God.” – Zechariah 8:2-8 NLT

While Jerusalem remained relatively empty and more work needed to be done, this was a day of celebration. God had done the impossible. He had used a small remnant of former captives to complete a massive construction project in record time and against all odds. Nehemiah had provided the plan and oversight of the effort, but he knew God deserved all the glory. So, in preparation for the big day, he arranged for Levites from all over Judah to join him in Jerusalem for the dedication. This was going to be an all-hands-on-deck event requiring the presence of every priest and Levite to pull off. The day would feature music, singing, sacrifices, offerings, and a special dedication service.

It all began with a massive purification ceremony.

The priests and Levites first purified themselves; then they purified the people, the gates, and the wall. – Nehemiah 12:30 NLT

Nothing could be done until the priests and the people had been consecrated. The worship of Yahweh would be useless if the proper cleansing ceremonies were neglected. The sequence of the purification ceremony is vital. First, the priests had to be cleansed so they could enter into God’s presence as mediators. Once purified, they were able to perform the necessary rites to cleanse the people. Finally, they purified the recently completed gates and walls.

For God to show up, the people and the place needed to be cleansed from sin. In essence, this elaborate ceremony was designed to decontaminate Jerusalem so that God could dwell there once more. This entire purification process began in the Temple. Leviticus 4 describes the steps necessary to remove corruption from the priests, people, and places so that God could dwell in their midst.

“If the high priest sins, bringing guilt upon the entire community, he must give a sin offering for the sin he has committed. He must present to the Lord a young bull with no defects. He must bring the bull to the Lord at the entrance of the Tabernacle, lay his hand on the bull’s head, and slaughter it before the Lord. The high priest will then take some of the bull’s blood into the Tabernacle, dip his finger in the blood, and sprinkle it seven times before the Lord in front of the inner curtain of the sanctuary. The priest will then put some of the blood on the horns of the altar for fragrant incense that stands in the Lord’s presence inside the Tabernacle. He will pour out the rest of the bull’s blood at the base of the altar for burnt offerings at the entrance of the Tabernacle. Then the priest must remove all the fat of the bull to be offered as a sin offering. This includes all the fat around the internal organs, the two kidneys and the fat around them near the loins, and the long lobe of the liver. He must remove these along with the kidneys,  just as he does with cattle offered as a peace offering, and burn them on the altar of burnt offerings. But he must take whatever is left of the bull—its hide, meat, head, legs, internal organs, and dung—and carry it away to a place outside the camp that is ceremonially clean, the place where the ashes are dumped. There, on the ash heap, he will burn it on a wood fire.” – Leviticus 4:3-12 NLT

While the Temple is not mentioned in Nehemiah 12, no cleansing ceremony could have taken place without the above-mentioned step occurring first. Sin was a barrier to God’s presence and Nehemiah knew that both he and his people were guilty and in need of cleansing. The past two months had been difficult and filled with every opportunity to violate God’s commands. There is little doubt that some, if not all, of Paul’s list of sins of the flesh happened as they worked on the wall.

…sexual immorality, impurity, lustful pleasures, idolatry, sorcery, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, division, envy, drunkenness, wild parties, and other sins like these. – Galatians 5:19-21 NLT

Tempers flared. Some escaped the drudgery through acts of sexual sin. Weary workers imbibed a bit too much alcohol at the end of the day to ease the pain and monotony of their labor. A lot can happen in two months. So, if the people wanted to enter into God’s presence and proclaim His goodness and greatness, they had to be cleansed. And because their sins infected anything and everything, the city and its walls also needed to be decontaminated.

Once all had been purified, the processional began. Nehemiah “led the leaders of Judah to the top of the wall and organized two large choirs to give thanks” (Nehemiah 12:31 NLT). These two groups began at the same place but then marched in opposite directions along the wall, singing and worshiping as they went. The plan was to meet again at a spot along the wall nearest the Temple.

The two choirs that were giving thanks then proceeded to the Temple of God, where they took their places. So did I, together with the group of leaders who were with me. We went together with the trumpet-playing priests—Eliakim, Maaseiah, Miniamin, Micaiah, Elioenai, Zechariah, and Hananiah—and the singers—Maaseiah, Shemaiah, Eleazar, Uzzi, Jehohanan, Malkijah, Elam, and Ezer. They played and sang loudly under the direction of Jezrahiah the choir director. – Nehemiah 12:40-42 NLT

What followed was a joyous and boisterous celebration, replete with sacrifices and loud singing. Nehemiah states that “the joy of Jerusalem was heard far away” (Nehemiah 12:43 ESV). Jerusalem was one big party as the people celebrated, sang, danced, and delighted in all Yahweh had done for them. The noise could be heard from miles around, and Sanballat and Tobiah must have been beside themselves with rage as they listened to the din rising from inside the newly constructed walls. Their worst fears had come true. The people of Judah had done the improbable and now they were celebrating their God who had made it all possible.

Inside the walls, the people were ecstatic. They could barely contain their joy as they considered what God had done. But it would have benefited them to consider the words spoken by God through Zechariah.

“For this is what the Lord of Heaven’s Armies says: I was determined to punish you when your ancestors angered me, and I did not change my mind, says the Lord of Heaven’s Armies. But now I am determined to bless Jerusalem and the people of Judah. So don’t be afraid. But this is what you must do: Tell the truth to each other. Render verdicts in your courts that are just and that lead to peace. Don’t scheme against each other. Stop your love of telling lies that you swear are the truth. I hate all these things, says the Lord.” – Zechariah 8:14-17 NLT

While the walls had been completed, their work was far from done. Jerusalem was once again a city and it would soon be populated with citizens. But one day of worship and celebration would not be enough. God wanted heart change. He expected His people to live set-apart lives every day of the year. As their ancestors had learned, the Temple, walls, and gates provided no protection from the wrath of God when His people refused to obey His commands. Whether they realized it or not, their most difficult days were ahead of them, not behind them.
