26. καὶ ὁ νικῶν καὶ ὁ τηρῶν. “He that overcometh and he that keepeth” are one; in most parts of the New Testament there would only be one article. This is the only passage where the promise to him that overcometh is introduced by καί. Here and Rev 3:12 and Rev 3:21 the writer begins with a nominative which has no regular construction.
τὰ ἔργα μου. “Such works as I do” is the sense, rather than “such as I approve.” Cf. Joh 14:12 “the works that I do shall he do also.”
