Is cornerstone mentioned in the Bible?

Answer 1

Yes. The most prominent mentions are: Isaiah 28:16 -Therefore thus says the Lord God: "Behold, I lay in Zion a stone for a foundation, A tried stone, a precious cornerstone, a sure foundation; Whoever believes will not act hastily." Ephesians 2:20 - having been built on the foundation of the apostles and prophets, Jesus Christ Himself being the chief cornerstone, 1 Peter 2:6 - Therefore it is also contained in the Scripture, "Behold, I lay in Zion A chief cornerstone, elect, precious, And he who believes on Him will by no means be put to shame." (NKJV)
