1 Peter 2:6

“Wherefore also it is contained in the Scripture, etc.] (<232816>Isaiah 28:16). This is produced as a proof of the excellency of Christ, as compared to a stone; and of his usefulness in the spiritual building; and of his being chosen of God, and precious, though rejected by men; and of the happiness, comfort, and safety of those that believe in him. That this prophecy belongs to the Messiah, is the sense of some of the Jewish writers: the Targum on it applies it to a mighty king; it does not mention the King Messiah, as Galatinus f48 cites it; but Jarchi expressly names him, and interprets it of him: behold, I lay in Sion a chief corner stone, elect, precious; Christ is here called a chief…”

“Wherefore also--The oldest manuscripts read, "Because that." The statement above is so "because it is contained in Scripture." Behold--calling attention to the glorious announcement of His eternal counsel. elect--so also believers (Pe1 2:9, "chosen," Greek, "elect generation"). precious--in Hebrew, Isa 28:16, "a corner-stone of preciousness." See on Isa 28:16. So in Pe1 2:7, Christ is said to be, to believers, "precious," Greek, "preciousness." confounded--same Greek as in Rom 9:33 (Peter here as elsewhere confirming Paul's teaching. See Introduction; also Rom 10:11), "ashamed." In Isa 28:16, "make haste," that is, flee in sudden panic, covered with the shame of confounded hopes.”

“Wherefore also it is contained in the scripture - Isaiah 28:16. The quotation is substantially as it is found in the Septuagint. Behold, I lay in Sion - See the Isaiah 28:16 note, and Romans 9:33 note. A chief cornerstone - The principal stone on which the corner of the edifice rests. A stone is selected for this which is large and solid, and, usually, one which is squared, and worked with care; and as such a stone is commonly laid with solemn ceremonies, so, perhaps, in allusion to this, it is here said by God that he would lay this stone at the foundation. The solemnities attending this were those which accompanied the great work of the Redeemer. See the word explained in the notes at…”

“He that believeth shall not be confounded - In time or in eternity. Isa 28:16. 1 Peter 2:7”

“2:6-8 The three Old Testament quotations in these verses each identify Christ as some kind of stone: the cornerstone on which the new temple is built (2:6); the cornerstone that God, despite peoples’ rejection, has elevated to be the keystone of his redemptive plan (2:7); and the stone that makes people stumble (2:8). Jesus quotes Ps 118:22 (Matt 21:42), and Paul quotes both Isa 8:14 and 28:16 (Rom 9:33). Likely these three quotations were brought together very early as a combined Old Testament testimony to the nature and significance of Jesus the Messiah.”
