David in the Old Testament trusted God daily.
Psalm 16:
Keep me safe, O God,
for I have come to you for refuge.
2 I said to the Lord, “You are my Master!
Every good thing I have comes from you.”
3 The godly people in the land
are my true heroes!
I take pleasure in them!
4 Troubles multiply for those who chase after other gods.
I will not take part in their sacrifices of blood
or even speak the names of their gods.
5 Lord, you alone are my inheritance, my cup of blessing.
You guard all that is mine.
6 The land you have given me is a pleasant land.
What a wonderful inheritance!
7 I will bless the Lord who guides me;
even at night my heart instructs me.
8 I know the Lord is always with me.
I will not be shaken, for he is right beside me.
