This one is not “psalm” of David, but a “miktam” attributed to him. It sounds like it should be something else, but we don’t appear to have an actual definition of what it is because the definition is just that it’s a word that’s used in psalm titles.
1Preserve me, O God, for in you I take refuge.
2I say to the LORD, “You are my Lord;
I have no good apart from you.”
3As for the saints in the land, they are the excellent ones,
in whom is all my delight.
4The sorrows of those who run after another god shall multiply;
their drink offerings of blood I will not pour out
or take their names on my lips.
5The LORD is my chosen portion and my cup;
you hold my lot.
6The lines have fallen for me in pleasant places;
indeed, I have a beautiful inheritance.
7I bless the LORD who gives me counsel;
in the night also my heart instructs me.
8I have set the LORD always before me;
because he is at my right hand, I shall not be shaken.
9Therefore my heart is glad, and my whole being rejoices;
my flesh also dwells secure.
10For you will not abandon my soul to Sheol,
or let your holy one see corruption.
11You make known to me the path of life;
in your presence there is fullness of joy;
at your right hand are pleasures forevermore.
This is a fairly straightforward praise and worship psalm that reads much like a modern praise band song. I didn’t appreciate the fourth verse calling out other people. I get the need to do so but I felt like it detracted from the rest of the psalm. It’s otherwise the kind of psalm for when you’re in a good mood and appreciate life but probably need more at other times.
