Jamieson, Fausset & Brown, on 1Pet 2:6

“Wherefore it is said in the scripture: Behold, I lay in Sion a chief corner stone, elect, precious. And he that shall believe in him, shall not be confounded.”

“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.”
