Capstone

Capstone

An architectural term denoting the top stone in a building or wall. If it caps an arch it is called a keystone. The expression is used twice in the Old Testament ( Psalm 118:22 ; Zech 4:7 ). In Zechariah 4:7 it is clearly the capstone of the temple that is in view. The meaning in Psalm 118:22 is less clear ("keystone" JB; "capstone" NIV; "cornerstone" NRSV). The Hebrew is translated by the Septuagint as kephalen gonias, literally, "the head of the corner." This term has made its way into the New Testament five times ( Matt 21:42 ; Mark 12:10 ; Luke 20:17 ; Acts 4:11 ; 1 Peter 2:7 ). Psalm 118:22 evidently refers to the king who was disallowed, but then acknowledged to be the rightful ruler. Jesus makes use of this psalm in a parable referring to Israel and its rejection of him as Messiah ( Matt 21:33-44, ; and parallels). In Acts 4:11 Peter makes use of Psalm 118:22 to defend himself against his Jewish detractors.

In all these passages it must be acknowledged that "capstone" or "cornerstone" would make an equally good translation. It is 1pe 2:7 that tips the scales toward "cornerstone." These three passages ( Psalm 118:22 ; Isa 8:14 ; 28:16 ) are used together to make the point that Christ is supreme, and two of these passages ( Isa 28:16 ; 8:14 ) clearly refer to a cornerstone.

So the Zechariah 4:7 passage is clearly "capstone" but the remainder are probably best taken as "cornerstone, " with the point being that Jesus was rejected by the ones who ought to have known him (builders = Jewish leadership), but God has exalted him to be the chief stone above all, the very head of the corner, on which all else depends.
