Back to lamenting...but I must say this one hits a little different for me. Also, we are doing 9 and 10 together because most translations agree that in the original manuscripts the two were combined. Psalm 10 does not have an author listed, but it does fit with 9. It seems like a completion of thought. No one mentioned why it was split by the original translators. Chronologically this is put in sometime at the end of David's life, fitting in somewhere at the end of 1 Chronicles, around chapter 21.
