Psalm 86

A prayer of David.

¹ Hear me, Lord, and answer me,
    for I am poor and needy.
² Guard my life, for I am faithful to you;
    save your servant who trusts in you. 
You are my God; ³ have mercy on me, Lord,
    for I call to you all day long.
⁴ Bring joy to your servant, Lord,
    for I put my trust in you.

⁵ You, Lord, are forgiving and good,
    abounding in love to all who call to you.
⁶ Hear my prayer, Lord;
    listen to my cry for mercy.
⁷ When I am in distress, I call to you,
    because you answer me.

⁸ Among the gods there is none like you, Lord;
    no deeds can compare with yours.
⁹ All the nations you have made
    will come and worship before you, Lord;
    they will bring glory to your name.
¹⁰ For you are great and do marvelous deeds; 
    you alone are God.

¹¹ Teach me your way, Lord,
    that I may rely on your faithfulness; 
give me an undivided heart,
    that I may fear your name.
¹² I will praise you, Lord my God, with all my heart; 
    I will glorify your name forever.
¹³ For great is your love toward me;
    you have delivered me from the depths,
    from the realm of the dead.

¹⁴ Arrogant foes are attacking me, O God;
    ruthless people are trying to kill me—
    they have no regard for you. 
¹⁵ But you, Lord, are a compassionate and gracious God,
    slow to anger, abounding in love and faithfulness. 
¹⁶ Turn to me and have mercy on me;
    show your strength in behalf of your servant;
save me, because I serve you    just as my mother did. 
¹⁷ Give me a sign of your goodness,
    that my enemies may see it and be put to shame,
    for you, Lord, have helped me and comforted me.

Amen
