One of my favourite pieces of music is the Parry arrangement of "I was Glad" (Ps.122) -- very uplifting to read the verses in today's Psalm.
Thanks be to God.
1 [Psalm 122] A song of Zion, sung by pilgrims obeying the law to visit Jerusalem three times on a journey. The singer anticipates joining the procession into the city (Psalm 122:1-3). Jerusalem is a place of encounter, where the people praise God (Psalm 122:4) and hear the divine justice mediated by the king (Psalm 112:5). The very buildings bespeak God's power (cf Psalm 48:13-15). May the grace of this place transform the people's lives (Psalm 112:6-9)!
2 [3] Walled round about: literally, "which is joined to it," probably referring both to the density of the buildings and to the dense population.
I think we could start posting the entire psalm, what do you think?
