While flipping through the Psalms months ago (to find Psalm 62:11 and confirm its resemblance to portions of Proverbs 30, which I was reading at the time), I happened to glance at a section of Psalm 46, and I noticed that the imperative verbs in the first part of verse 10 are stative:
'Be still, and know that I am God.'
The static nature of these verbs (especially in contrast to active voice verbs) matches the tranquility that they encourage in this context.
