Responsorial Psalm
Ps 51:3-4, 12-13, 18-19

R. (19b) A heart contrite and humbled, O God, you will not spurn.
Have mercy on me, O God, in your goodness;
in the greatness of your compassion wipe out my offense.
Thoroughly wash me from my guilt
and of my sin cleanse me.
R. A heart contrite and humbled, O God, you will not spurn.
A clean heart create for me, O God,
and a steadfast spirit renew within me.
Cast me not out from your presence,
and your Holy Spirit take not from me.
R. A heart contrite and humbled, O God, you will not spurn.
For you are not pleased with sacrifices;
should I offer a burnt offering, you would not accept it.
My sacrifice, O God, is a contrite spirit;
a heart contrite and humbled, O God, you will not spurn.
R. A heart contrite and humbled, O God, you will not spurn.
