11:1 As a principle of life David sought refuge from his enemies in the Lord, his stronghold. Consequently when his counselors urged him to run and hide in a physical stronghold, he refused to do so (cf. Matt. 16:22; Acts 21:12). He regarded Yahweh a much more secure refuge than any fortress.
11:2 The wicked were attacking the upright and David in particular. He was the target of their deadly missiles. They may have been shooting at him or he may have been under verbal attack.
11:3 David's faint-hearted counselors evidently felt the very foundations of their nation where in danger of being destroyed, namely the Mosaic Law and the institutions of Judaism. They felt distressed to the point of distraction over this possibility. Many faint-hearted people behave similarly today when they see foundational elements of their society under attack.
