A psalm of David.
1 O Lord, I call to you; come quickly to me.
Hear my voice 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, O Lord;
keep watch over the door of my lips.
4 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.
