This article is about The Prophet. You may be looking for The Tribe of Gad or The Patriarch, whom it was named for.
Gad first appears in the Bible to persuade David to leave his place of safety in Moab and return to Tribe of Judah, where the insanely jealous King Saul awaited him. later on, after David had a census taken of Israel, Gad gave David a choice of punishments from God for carrying out that rash act. David chose the three day plague.
During the plague, which took 70,000 lives, Gad, the prophet, told David to build an altar to God on the threshing floor of Araunah the Jebusite.[1] The burnt offerings from this altar, caused the Lord to stop the plague. The threshing floor, later, became the site of King Solomon's Temple. Gad, along with David and the prophet Nathan,[2] Gad is described as David's seer.[3]
