1 Peter 2:8

“And a stone of stumbling, and a rock of offence, etc.] The apostle alludes to (<230814>Isaiah 8:14) and which is a prophecy of the Messiah; (see Gill on “ <450933>Romans 9:33”) and had its accomplishment in the unbelieving and disobedient Jews; who stumbled at his birth and parentage; at the manner of his birth, being born of a virgin; at the meanness of his parents, his supposed father being a carpenter, and his mother, Mary, a poor woman, when they expected the Messiah would have sprung from some rich and noble family; and at the place of his birth, which they imagined was Galilee, from his education and conversation there; they stumbled also at his education, and could not conceive how he…”

They refuse to build on him, and it is as if one should run against a solid projecting cornerstone of a house, that would certainly be the means of their destruction. Compare the notes at Luke 2:34. An idea similar to this occurs in Matthew 21:44; “Whosoever shall fall on this stone shall be broken.” The meaning is, that if this foundation-stone is not the means…”

“Who stumble, whereunto also they were appointed - They who believe not, stumble, and fall, and perish for ever; God having appointed from all eternity, "he that believeth not shall be damned." 1 Peter 2:9”

“a stone: Isa 8:14, Isa 57:14; Luk 2:34; Rom 9:32, Rom 9:33; Co1 1:23; Co2 2:16 being: Pe1 2:7 whereunto: Exo 9:16; Rom 9:22; Th1 5:9; Pe2 2:3; Jde 1:4 1 Peter 2:9”
