One quick point. David said that in his panic or emotional state, that in haste he spoke in unbelief, “I am cut off.”
Remember the story about being on the doorstep of the Promise Land? There Joshua and the children of Israel both spoke. Joshua spoke a word faith, but the Israelites spoke in their haste a word of unbelief, “we can’t do this.”
God judged the Israelites harshly. David, after realizing his mistake, confesses to God. God helps David according to His promise. If you are one of God’s elect, do not let a hastily spoken word be the end. While it is still today, repent and exchange that word of unbelief for a word of faith, and keep saying it.
[NLT] God will help. He is faithful to uphold His promises.–
LORD, I seek refuge in You;
let me never be disgraced.
Save me by Your righteousness.
Listen closely to me; rescue me quickly.
Be a rock of refuge for me,
a mountain fortress to save me.
For You are my rock and my fortress;
You lead and guide me
because of Your name.
You will free me from the net
that is secretly set for me,
for You are my refuge.
Into Your hand I entrust my spirit;
You redeem me, LORD, God of truth.
I hate those who are devoted to worthless idols,
but I trust in the LORD.
I will rejoice and be glad in Your faithful love
because You have seen my affliction.
You have known the troubles of my life
and have not handed me over to the enemy.
You have set my feet in a spacious place.
Be gracious to me, LORD,
because I am in distress;
my eyes are worn out from angry sorrow—
my whole being as well.
Indeed, my life is consumed with grief
and my years with groaning;
my strength has failed
because of my sinfulness,
and my bones waste away.
I am ridiculed by all my adversaries
and even by my neighbors.
I am dreaded by my acquaintances;
those who see me in the street run from me.
I am forgotten: gone from memory
like a dead person—like broken pottery.
I have heard the gossip of many;
terror is on every side.
When they conspired against me,
they plotted to take my life.
But I trust in You, LORD;
I say, “You are my God.”
The course of my life is in Your power;
deliver me from the power of my enemies
and from my persecutors.
Show Your favor to Your servant;
save me by Your faithful love.
LORD, do not let me be disgraced when I call on You.
Let the wicked be disgraced;
let them be silent in Sheol.
Let lying lips be quieted;
they speak arrogantly against the righteous
with pride and contempt.
How great is Your goodness
that You have stored up for those who fear You
and accomplished in the sight of everyone
for those who take refuge in You.
You hide them in the protection of Your presence;
You conceal them in a shelter
from the schemes of men,
from quarrelsome tongues.
May the LORD be praised,
for He has wonderfully shown His faithful love to me
in a city under siege.
In my [haste] I had said,
“I am cut off from Your sight.”
But You heard the sound of my pleading
when I cried to You for help.
Love the LORD, all His faithful ones.
The LORD protects the loyal,
but fully repays the arrogant.
Be strong and courageous,
all you who put your hope in the LORD.
