1. The Prophet. Very little is known concerning Haggai. He was a contemporary (Ezra 6:14) and colleague of Zechariah. His reference to the first Temple (Haggai 2:3) has been made the basis for a not improbable inference that he was a very old man at the time of his public prophesying, one who had outlasted the Babylonian exile. But, like many others through whom God has spoken, we know Haggai only through the messages he delivered.
