This has some pretty poetry (“Keep me as the apple of the eye, hide me under the shadow of thy wings” v 8 KJV) but otherwise it’s just another rant on the same theme – David sucking up to god, begging for attention, and asserting his righteousness as compared to all those other wicked people out there.
This psalm is very similar to 2 Samuel 22. It’s also vaguely familiar; I probably sang or recited it in church at one time. The beginning is exactly the sort of verse Christians cherry-pick: “The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust …” (v 2 KJV) How lovely! But keep reading – v 7 – 15 describe a very violent god, causing (I think) a volcano, from the description. That’s what Yahweh will do to your enemies! And v 20 – 24 are more of David’s smugness and egotism. Enough, already!
Some lovely poetry in this one (or sappy, depending on your bent), and it has spawned a number of contemporary Christian pop songs (go to YouTube and search for Psalm 19; I listened to portions of several but I’ll spare you). It also contains some quaint examples of prescientific thinking, like “The sun rises at one end of the heavens and follows its course to the other end.” (v 6 NLT)
This one gets only a zzzzz icon (boring) from the SAB, and I would have to agree. Nothing new here. Move on.
