Psalm 27
It opens in bold confidence ("whom shall I fear?") and then, in the second half, sounds more fragile: "Hide not Your face... do not leave me." Both are true in one heart. The single desire is to gaze on God's beauty. Even if father and mother forsake, the LORD receives. It ends with waiting, said twice.
"One thing I have asked of the LORD; this is what I desire: to dwell in the house of the LORD all the days of my life, to gaze on the beauty of the LORD and seek Him in His temple." (Psalm 27:4)
Versions/Hebrew: "Wait patiently" in 27:14 is qavveh [6960], related to the word for a cord, to wait with tension and expectation; YLT "Look unto Jehovah."
