1 Peter 2:6

‘For it stands in scripture: “See, I am laying in Zion a stone, a cornerstone chosen and precious; and whoever believes in him will not be put to shame.”’

Peter is quoting from the Old Testament, Isaiah 28:16: ^“therefore thus says the Lord God, See, I am laying in Zion a foundation stone, a tested stone, a precious cornerstone, a sure foundation: “One who trusts will not panic.” and also from Isaiah 45:17, ^“But Israel is saved by the Lord with everlasting salvation; you shall not be put to shame or confounded to all eternity.”

There is a conflation of the verses going on, and Peter is adding a new dimension to their interpretation, that of Jesus as the fulfillment of their meanings.  We will look at the context of the two verses as we explore this sentence.

For it stand in scripture-Peter is looking to the authority of the bible that they had, what we call our Old Testament.

See, I am laying in Zion a stone, a cornerstone chosen and precious…this is the passage from Isaiah 28, in brief.

And whoever believes in him will not be put to shame.  This concludes the sentence, coming from Isaiah 45.

How Peter puts them together in this ‘modern’ (for him) formulation we can contrast against the original prophecies in Isaiah.
