Therefore thus says the Lord GOD,
Behold, I lay in Zion for a foundation a stone, a tested stone, a precious cornerstone, a sure foundation: he that believes shall not be in haste.
All Commentaries on Isaiah 28:16 Go To Isaiah 28
Augustine of Hippo
AD 430
A stone anointed; why a stone? “Behold, I lay in Zion a stone, elect, precious; and he that believes on him shall not be confounded.” Why anointed? Because Christ comes from “anointing” (chrisma).
