A prayer of David; Hear, O LORD, what is just, attend to my cry, incline Your ear to my prayer, which is not from lips of deceit.
MIDRASH TEHILLIM
1.....(17.2) ...Hear, O LORD...
...as if David was saying to God, Master of the universe, if in the morning of the Day of Atonement, before i say my prayers, You cause Your judgment of me to come forth, I will be unable to stand up. Let me first read the Shema.
