In Vetere Novum Lateat

In Old, New Latent

To the faithful you show yourself faithful, to the blameless you show yourself blameless, to the pure you show yourself pure, but to the devious you show yourself shrewd. You save the humble but bring low those whose eyes are haughty. Psalms 18:25‭-‬27

There are so many passages which draw from this duplicate davidic Psalm

Among which

God opposes the proud
Gives grace to the humble

If we are faithless
He remains faithful

To the pure
All things are pure

Et al.

What are some other passages which draw specifically on this psalm both here and in the history of Samuel?
