Cast not away - implying that they now have “confidence,” and that it will not withdraw of itself, unless they “cast it away” willfully (compare Heb 3:14).
which - Greek, “the which”: inasmuch as being such as.
hath - present tense: it is as certain as if you had it in your hand (Heb 10:37). It hath in reversion.
