This litany is taken directly from Isaiah 58, Psalm 112, and from Jesus’ Sermon on the Mount iMatthew 5. Each of those is part of the Lectionary selection for the Fifth Sunday of Epiphany.

Merciful God,
We receive your instructions about what pleases you:
To loose the bonds of injustice,
To free the oppressed,
To share bread with the hungry,
To provide shelter for the homeless poor,
To cover the naked,
To be present to our kin. (1)

You have said: “If you offer your food to the hungry
And satisfy the needs of the afflicted,
Then your light shall rise in the darkness
And your gloom be like the noonday.” (2)

You have said: “It is well with those who deal generously,
Who conduct their affairs with justice.
They are not afraid of evil tidings;
Their hearts are steady;
They have distributed freely, they have given to the poor;
In the end they will look in triumph on their foes.” (3)

We acknowledge that what is wisdom to you seems like foolishness to the world;
    That the commands and example of Jesus seem ridiculous, and risky;
    That if our goal is to save our own lives, we will lose them;
    That, in your kingdom, giving is better than getting. (4)

Lord, give us strength.
We are the salt of the earth.
Lord, give us wisdom.
We are the light of the world.
Let our light shine brightly,
So all may see the goodness of God. (5)

Amen
