A psalm of David.

1 I call to you, LORD, come quickly to me; hear me when I call to you.
2 May my prayer be set before you like incense; may the lifting up of my hands be like the evening sacrifice.
3 Set a guard over my mouth, LORD; keep watch over the door of my lips.

4 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.
