A Sunday Psalm

Hear, O Lord, and answer me, for I am poor and needy.
Guard my life, for I am devoted to You.
You are my God; save Your servant who trusts You.
Have mercy on me, O Lord, for I call to You all day long.
Bring joy to Your servant, for to You, O Lord, I lift up my soul.
        --Psalm 86:1-4
