Nathan (prophet) in Wikipedia

Nathan the Prophet (fl. c. 1000 BC) was a court prophet who lived in the time of King David and Queen Bathsheba. He came to David to reprimand him over his committing adultery with Bathsheba while she was the wife of Uriah the Hittite whose death the King had also arranged to hide his previous transgression. His actions are described in the Books of Samuel, Kings, and Chronicles (see especially, 2 Samuel 7:2-17 , 12:1-25 .) Nathan wrote histories of the reigns of both David and of Solomon (see 1 Chronicles 29:29 and 2 Chronicles 9:29 ), and was involved in the music of the temple (see 2 Chronicles 29:25). In 1 Kings 1:8-45 it is Nathan who tells the dying David of the plot of Adonijah to become king, resulting in Solomon being proclaimed king instead. The feast day of Nathan the Prophet is on 24 October. In the Eastern Orthodox Church, and those Eastern Catholic Churches which follow the Byzantine Rite, he is commemorated as a saint on the Sunday of the Holy Fathers (i.e., the Sunday before the Great Feast of the Nativity of the Lord).
