This psalm is about a very small group—the Levites who served as Temple watchmen. Singing this psalm, the last of the "songs of ascent" (Psa 120-134), the worshipers would ascend the hill where the Temple sat and see the watchmen who protected it day and night. They saw the watchmen's work as an act of praise to God, done reverently and responsibly. Make your job or your responsibility in the church an act of praise by doing it with reverence to God. Honor him by the quality of your work and the attitude of service you bring to it.
