Psalms 134
The Psalter's shortest call to bless the Lord at night.
Psalm 134 is the final and shortest of the songs of ascent, calling on the servants "which by night stand in the house of the LORD" to lift their hands in the sanctuary and bless Him. It closes the sequence begun many chapters earlier, following directly after Psalms 133's picture of unity.
Behold, bless ye יהוה, all ye servants of יהוה, which by night stand in the house of יהוה.
Lift up your hands in the sanctuary, and bless יהוה.
יהוה that made heaven and earth bless thee out of Zion.
