Have you ever rediscovered a forgotten command of God and felt a fresh wave of joy? This passage describes a moment like that, a revival sparked by obedience.
The people of Israel, returning from Babylonian captivity, had largely forgotten the Feast of Tabernacles, a command given to them long ago. Though the feast itself had been observed in some form since Joshua's time, this particular celebration was unprecedented in its scale and enthusiasm. The scholars point out that 'done so' doesn't mean the feast was never kept, but that it was never kept with this level of joyful, comprehensive obedience. It was a deliberate, communal return to God's specific instructions, marked by a profound sense of gladness.
