He was a Galilean of the tribe of Simeon. The Old Testament book that bears his name foretells the destruction of Nineveh, the capital of Assyria, by the Medes, and the restoration of the Kingdom of Judah; all of this came to pass. Nahum is counted as the seventh of the Minor Prophets. He reposed in peace. His name means 'consolation' or 'repose.'

Five of the Prophets (Nahum, Habbakuk, Zephaniah, Haggai, and Daniel) are commemorated in December. At one time a Feast of the Twelve Prophets was celebrated on December 4 at the Church of the Resurrection, but this feast is no longer on the calendar. The days leading up to Christ's Nativity contain many commemorations of the faithful remnant of Israel, all of whose hopes were fulfilled in the birth of the Messiah.
