In Neh. 6:15-16 and 12:27-43 we have the joyous conclusion to the Jerusalem wall-building project. Those events can be summarized with these four concepts:
1. The SPEED of project completion. (6:15)
2. The HUMILIATION of the enemies. (6:16)
3. The PURITY of the worshippers. (12:30)
4. The REJOICING in the Lord. (12:27-43)
