I call to you, Lord, come quickly to me; hear me 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, Lord; keep watch over the door of my lips.
Do not let my heart be drawn to what is evil so that I take part in wicked deeds
along with those who are evildoers; do not let me eat their delicacies.
Psalm 141:1-4 (NIV)
