Thus saith the LORD of hosts; Let your hands be strong, ye that hear in these days these words by the mouth of the prophets, which were in the day that the foundation of the house of the LORD of hosts was laid, that the temple might be built. By the mouth of the prophets - The day or time of the foundation was about two years before, as this discourse of the prophet was in the fourth year of Darius. After this God raised up prophets among them.
