1 tn Grk “answering, Jesus said to him.” The participle ἀποκριθείς (apokriqeis) is redundant, but the syntax of this phrase has been modified for clarity.
2 tn The expression “flesh and blood” could refer to “any human being” (so TEV, NLT; cf. NIV “man”), but it could also refer to Peter himself (i.e., his own intuition; cf. CEV “You didn’t discover this on your own”). Because of the ambiguity of the referent, the phrase “flesh and blood” has been retained in the translation.
