According to the Book of Psalms, what is the shortest psalm?

According to the Book of Psalms, Psalm 117 is the shortest psalm.

In the Hebrew numbering used by most Jewish and Protestant Bibles, Psalm 117 contains only two verses. It calls all nations to praise the Lord and grounds that praise in divine steadfast love and faithfulness. Its brevity makes it one of the most frequently cited numerical facts about the Psalter.

Psalm 117 is also the middle chapter of the Protestant Bible in its traditional chapter arrangement. That central-position claim depends on counting conventions and editions, but the psalm’s two-verse length is stable in standard translations.

Psalm 23 is much longer and is famous for its shepherd imagery. Psalm 150 is the closing psalm and contains a series of praise commands. Psalm 1 opens the collection but is not the shortest. Verse numbering can vary slightly between traditions, yet Psalm 117 remains the briefest psalm in the usual biblical text.
