What does Psalm 55:7 mean?

David affirms his deep desire to flee from trouble (Psalm 55:6). Given the chance, he would grow wings and literally fly from danger, far away from civilization and its troubles. Other staunch believers, such as Elijah, faced similar levels of panic (1 Kings 19) yet they, too, resolved to maintain their faith in God in the end (Psalm 55:16). David's fear-driven desire to escape ungodly enemies is understandable.

While David sought to fly from danger, in the form of a dove, the prophet Jonah tried to flee from God's direct command—and Jonah's name means "dove." He was afraid the Ninevites, against whom he wanted to predict judgment, might repent and receive God's forgiveness (Jonah 1:2; 4:1–3). So, he boarded a ship that was sailing far to the west, whereas Nineveh was in the east (Jonah 1:3). Of course, Jonah learned a hard lesson, through a massive sea creature, that it is futile to flee from God (Jonah 2).

This verse includes the Hebrew term selah, which is not clearly understood. It seems to imply reflection, or a pause. In this case, it is appropriate. David is praying for rescue (Psalm 55:1–5) while hoping to find rest from his troubles (Psalm 55:6).
