Wesley's Notes on the Bible
<> Behold, bless ye the LORD, all ye servants of the LORD, which by night stand in the house of the LORD.
134:1 Servant - Peculiarly so called, priests and Levites. Night - Not only by day, but also by night, when their watch was more necessary. Stand - Serve or minister.
Lift up your hands in the sanctuary, and bless the LORD.
The LORD that made heaven and earth bless thee out of Zion.
134:3 Thee - Thee whosoever thou art who dost faithfully perform the duty here commanded.
