{Covered up} (sugkekalummenon estin). Periphrastic perfect
passive indicative of sugkalupt(935c), an old verb, but here only in
the N.T., to cover up on all sides and so completely. Verses
 2-9  here are parallel with  Mt 10:26-33  spoken to the Twelve
on their tour of Galilee, illustrating again how often Jesus
repeated his sayings unless we prefer to say that he never did so
and that the Gospels have hopelessly jumbled them as to time and
place. See the passage in Matthew for discussion of details.
