Psalm 134
A SONG OF ASCENTS.
1 Praise the Lord, all you servants of the Lord
who minister by night in the house of the Lord.
2 Lift up your hands in the sanctuary
and praise the Lord.
3 May the Lord bless you from Zion,
he who is the Maker of heaven and earth.

Because it’s the Holy City? Just a guess, my brain is fried.
Yes and He will bless the nations from that p-lace in the age to come.
Ah good, I was right 🙂
