Isaiah 53 Verse 10

[ThomasDGW]

why would anyone think that 118:22 has to do with a messianic figure?

The people are praising God for salvation from exile, getting ready to enter the temple, saying, Save now, Make prosperous now, and do they say in the middle of that, We have become the cornerstone???

I think that anyone who views this a bit incongruous would consider the possibility that the cornerstone could refer to the Messiah.
