Context: Psalm 141 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.
