Selah
This is a beautiful word that doesn't actually have an exact definition. Its context is powerful, used often throughout the Psalms, denoting a pause, a time of reflection and rest, usually in a passage in which the emotion of the writer is too great to continue without time to pause and recover. The Psalmist here is a man physically weighed down by his sin and his need for repentance and restoration. He is so heavily burdened, I can picture him on his hands and knees, crawling toward the feet of Jesus, bereft of strength, knowing that He is the only hope for help and salvation. He acknowledged his sin, covered nothing, confessed, and his strength was then restored.
