It happened, when Saul was returned from following the Philistines, that it was told him, saying, Behold, David is in the wilderness of En Gedi.
This little incident provides another window into David’s thinking. David was acknowledging Yahweh’s sovereignty by submitting to His authority in setting Saul up as king (cf. Proverbs 24:21). David refused to take revenge for the trouble that Saul had caused him.
