1 Samuel 22:3-4

David went thence to Mizpeh of Moab . The position of this place is unknown, but as the word means a watch tower, it was no doubt some beacon hill in the highlands of Moab on the east of the Dead Sea, and probably in the mountains of Abarim or Pisgah. Here David placed his father and mother under the care of the king of Moab. They had fled from Bethlehem under the combined fear of Saul and the Philistines, but were too old to bear the fatigues of David's life. He therefore asks for a refuge for them with the king of Moab, probably on the ground that Jesse's grandmother, Ruth, was a Moabitess. But as Saul had waged war on Moab ( 1 Samuel 14:47 ), the king was probably glad to help one who would keep Saul employed at home. The language of David is remarkable, and is literally, "Let, I pray, my father and my mother come forth with you" (pl.); but no better interpretation has been suggested than that in the A.V.: "Let them come forth, i.e. from the hold in Mizpeh, to be or dwell with you." While David was in the hold. Not merely that in the land of Moab, but up to the time when David was settled in Hebron. During all this period David was wandering from one natural fortress to another. Till I know what God will do for (or to) me . These words show that David had recovered his composure, and was willing calmly to leave everything to the wise disposal of God.
