Looking for article on wisdom/royal Psalm pairings


Puritanboard Clerk
There is an academic article, the title of which escapes me, that noted some psalms in the psalter were coupled together along the following themes:

wisdom psalm/royal psalm

Torah psalm/royal psalm

The obvious example is

Psalm 1: Meditates on God's Law
Psalm 2: The Son is enthroned

Psalm 19: Law of the Lord is perfect
Psalms 20-21: The king rejoices in your strength

If you remember the title of the article, could you share it? Thanks.
Not sure about the article but Palmer Robertson's book, The Flow of the Psalms, covers these kind of things. The article you are looking for is probably in his Bibliography.
