And believed.— The plain interpretation of this passage seems to be, that John entering into the sepulchre, saw every thing as above related, and consequently believed, not that Christ was risen, but that the body was taken away, as Mary Magdalene had informed them: for the apology which he immediately subjoins, evidently proves that a belief in the resurrection could not be meant; because St. John declares that they knew not, they had not the least idea of those scriptures which foretold his resurrection from the dead. See the note on Luke 24:11.
