Barnabas 6:2
Woe unto you, for ye all shall wax old as a garment, and the moth
shall consume you (Isaiah 51:8). And again the prophet saith, seeing that as a
hard stone He was ordained for crushing; Behold I will put into the
fountains of Zion a stone very precious, elect, a chief
corner-stone, honorable (Isaiah 28:16).

Understanding these contexts is crucial to Salvation.
