We can read this reminder as referring specifically to David's establishment of Jerusalem as the capital and the worship center for all the tribes. And we can also read it metaphorically--Israel welcomed being chosen by the Lord and responded in a way that we could call hospitable and respectful.
This psalm then asks the Lord to remember the promise of the covenant with the house of David. Note that the Bible has several references to the covenant's being eternal, here it is described in more conditional terms--"If your sons keep my covenant and my decrees ... their sons also, forevermore, shall sit on your throne."
We are reading this psalm this week as we prepare for Christ the King Sunday; therefore, of course, we read it as applying to our lives and our worship. We who are Christians can remember the promises made to David and we can appropriate many of them for ourselves.
We also can appropriate many of the pledges that David made. We do desire to find a place for the Lord in our lives, a place that may be for us a physical church building, but it is also that place within the hearts of all of us in community.
And we certainly can appropriate the verses praying that our clerics be clothed in righteousness and all of us faithful, clergy and lay, be joyful in the presence of the Lord.
The place that the Lord has chosen to dwell is a place that will receive many blessings.
The first is to feed the poor.
Others include granting salvation to the priests, providing prosperity for David's decendants, and heaping disgrace on his enemies.
Back to the first--feeding the poor.
If we were to assess whether our congregation is providing an appropriate dwelling place for the Lord, should we use as a criteria whether we are feeding the poor?
