I Peter 2:6

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.

The general exhortation to holiness is continued, and enforced by several reasons taken from the foundation on which Christians are built, Jesus Christ, and from their spiritual blessings and privileges in him. The means of obtaining it, the word of God, is recommended, and all contrary qualities are condemned (Pe1 2:1-12). Particular directions are given how subjects ought to obey the magistrates, and servants their masters, patiently suffering in well doing, in imitation of Christ (Pe1 2:13 to the end).

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.
