At the Voice of Stefan, the blogger has began a series of posts on this passage:
On that day I will raise up
the tent of Dauid that is fallen
and rebuild its ruins
and raise up its destruction,
and rebuild it as the days of old
in order that those remaining of humans
and all the nations upon whom my name has been called
might seek out me,
says the Lord who does these things. (NETS)
He sites Patristic evidence that the primitive Church saw this as referring to the Resurrection.
I have been taught, and have taught it myself, that this prophecy refers to the Church, but I am interested in seeing where it leads. Check it out, if you can.
