Ps. 134: Ascent of Servanthood

Psalm 134:3 "May the LORD, the Maker of heaven and earth, bless you from Zion."

This appears to be a reminder to the priests, and those who work in and around the sanctuary...whether that's the temple or the tabernacle to praise God. I wonder if they can get locked into some sort of monotony or autopilot on the "job," and forget why they are there, the reason for their servanthood. It's a reminder that God is real to them, and worthy of their praise as well. It's not just their responsibility to facilitate worship, but to participate in worship as well.
