Gad

"Gad (/ɡæd/) was a seer or prophet mentioned in the Hebrew Bible and the writings of Jewish historian Josephus. He was one of the personal prophets of King David of Israel and, according to the Talmudic tradition, some of his writings are believed to be included in the Books of Samuel. He is first mentioned in 1 Samuel 22:5 telling David to return from refuge in Moab to the forest of Hereth in the land of Judah.

The next biblical reference to Gad is 2 Samuel 24:11–13 (1 Chronicles 21:9–13) where, after David confesses his sin of taking a census of the people of Israel and Judah, God sends Gad to David to offer him a choice of three forms of punishment." - (en.wikipedia.org 30.12.2020)
