Psalm 3 belongs to king David and is entitled “A morning prayer of trust in God”. It is a Psalm that will teach us different things and the main thing is to recognize that salvation belongs to our God and not to ourselves:
1 Lord, how many are my foes! How many rise up against me!
2 Many are saying of me, “God will not deliver him.”
3 But you, Lord, are a shield around me, my glory, the One who lifts my head high.
4 I call out to the Lord, and he answers me from his holy mountain.
5 I lie down and sleep; I wake again, because the Lord sustains me.
6 I will not fear though tens of thousands assail me on every side.
7 Arise, Lord! Deliver me, my God! Strike all my enemies on the jaw; break the teeth of the wicked.
8 From the Lord comes deliverance. May your blessing be on your people.
This is not exactly the prayer we do every morning when we wake up, but we can make it a model in our day to day. In the first place we must understand that the psalmist David was a man who suffered much in the reign of king Saul, was persecuted by envy, despite David being a loyal, faithful and honorable man.
David makes a prayer to God telling him all the enemies he has: How many they rised up against him and they said about him: “God will not deliver him”. This reminds us when our Lord Jesus Christ was hanging on a tree, that those people who were there made fun of asking where his God was.
