Psalm 69
(Unto the end, a psalm for David, to bring to remembrance that the Lord saved him.)
O God, come to my assistance; O Lord, make haste to help me.
Let them be confounded and ashamed that seek my soul:
Let them be turned backward, and blush for shame that desire evils to me: Let them be presently turned away blushing for shame that say to me: Tis well, tis well.
Let all that seek thee rejoice and be glad in thee; and let such as love thy salvation say always: The Lord be magnified.
But I am needy and poor; O God, help me. Thou art my helper and my deliverer: O Lord, make no delay.

Prayer
Let us pray.
O God, it is according to thy nature always to show mercy and forgiveness.
Receive our petition that we and all thy servants, bound by the chains of sin, may, by thy tender mercy, be pardoned.
We beg thee, O Lord, hear our prayers as we kneel before thee. Pardon our sins, as we confess them to thee, so that thou mayest, in thy kindness, give us pardon as well as peace.
In thy kindness show us, O Lord, thy unutterable mercy, and at one and the same time free us from all our sins, and snatch us away from the punishment which we deserve for them.
O God, thou art offended by sin, and placated by penance. Look with favor upon the prayers of thy people kneeling before thee. Turn away the scourges of thine anger which we have deserved for our sins.
Almighty, everlasting God, have mercy on thy servant N., our Sovereign Pontiff. Direct him, according to thy mercy into the path of eternal salvation so that, by thy grace, he may both desire those things that are pleasing to thee, and may perform them with all his strength.
O God, from whom all holy desires, all good counsels, and all just works do proceed; Give unto thy servants that peace which the world cannot give, so that, with our hearts set to obey thy commandments, and freed from the fear of the enemy, we may pass our lives in peace under thy protection.
Inflame our hearts and our desires, O Lord, with the fire of the Holy Spirit, so that we may serve thee with a chaste body, and please thee with a pure heart.
O God, thou art the creator and redeemer of all the faithful. Grant to the souls of thy servants departed the remission of all their sins, so that by our faithful prayers they may obtain the pardon they have always desired.
We beg thee, O Lord, to direct our actions by thy holy inspiration, and carry them forward by thy gracious assistance, so that every prayer and work of ours may always begin with thee, and, begun through thee, be happily ended.
Almighty and everlasting God, who hast dominion over the living and the dead and who art merciful to all whom thou foreknowest shall be thine by faith and good works, we humbly beg of thee, that they for whom we have intended to pour out our prayers, whether this present world still detains them in the flesh, or whether the world to come has already received them out of their bodies, may, through the prayers of all thy saints, by thy merciful goodness obtain the remission of all their sins
Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end.
R. Amen.
V. O Lord, hear my prayer.
R. And let my cry come unto thee.
V. May the almighty and merciful Lord graciously hear us.
R. Amen.
V. May the souls of the faithful, through the mercy of God, rest in peace.
R. Amen.
