David went there to Mizpeh of Moab: and he said to the king of Moab, Please let my father and my mother come forth, [and be] with you, until I know what God will do for me.
Gad appears to have been a prophet who remained with David throughout his reign (cf. 2 Samuel 24:11). God provided another prophet through whom He communicated to the king-elect other than Samuel. The forest of Hereth was somewhere in Judah, but its exact location is unknown. [Note: On the alternate reading, "David . . . had departed," (1 Samuel 22:6), see D. Winton Thomas, "A Note on noda’ in I Samuel XXII. 6," Journal of Theological Studies 21:2 (October 1970):401-2.]
