Here is a responsorial psalm from the Jerusalem Bible version of Psalm 137 (which is Psalm 138 using the Masoretic numbering sequence), verses 1 to 3, and 7 to 8:

On the day I called, you answered me, O Lord.

I thank you, Lord, with all my heart:

  you have heard the words of my mouth.

In the presence of the angels I will bless you.

  I will adore before your holy temple.

On the day I called, you answered me, O Lord.

I thank you for your faithfulness and love,

  which excel all we ever knew of you.

On the day I called, you answered;

  you increased the strength of my soul.

On the day I called, you answered me, O Lord.

You stretch out your hand and save me,

  your hand will do all things for me.

Your love, O Lord, is eternal,

  discard not the work of your hands.

On the day I called, you answered me, O Lord.
