Then Nathan said to David: “You have done this deed in secret, but I will bring it about in the presence of all Israel, and with the sun looking down. Then David said to Nathan, “I have sinned against the LORD.” (2 Sam 12:1-7a, 10-17)

David’s anguish over his sin being found out and his subsequent contrition is expressed with great pathos in today’s Responsorial Psalm (Ps 51): Free me from blood guilt, O God, my saving God; create a clean heart in me. Today's photo is of the Black Madonna, Our Lady of Einsiedeln.
