Mark 12:10
Haven't you read this passage of Scripture: the stone the builders rejected has become the cornerstone — the citation of Psalm 118:22 (the same psalm sung at the triumphal entry) applies to Jesus the reversal promised in the psalm. The stone the builders rejected is the stone the builders considered unsuitable, useless, beneath consideration for a load-bearing role. The cornerstone (or capstone) is the most critical stone in the structure — the one everything else aligns with. The son rejected and killed becomes the cornerstone of what God is building.
