Ellicott's Commentary On The Whole Bible
Psalms 134 - Introduction
CXXXIV.
This little song, with its appeal and its response, fitly closes the Songs of the Steps. It is a challenge to the Levites going on duty for the night to praise Jehovah, as others have already done by day. For the importance of this psalm in deciding the date of the close of the Psalter, see General Introduction.
