A Sunday Psalm

O Lord, I call to You; come quickly to me.
Hear my voice when I call to You.
May my prayer be set before You like incense;
may the lifting up of my hands be like the evening sacrifice.
Set a guard over my mouth, O Lord;
keep watch over the door of my lips.
Let not my heart be drawn to what is evil,
to take part in wicked deeds with men who are evildoers;
let me not eat of their delicacies.
      --Psalm 140:1-4
