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 Jehovah, all ye servants of Jehovah, who stand by night in the house of Jehovah.
Lift up your hands to the sanctuary, and bless ye Jehovah.
Jehovah bless thee out of Zion, even he who made heaven and earth.
