A.T. Robertson Commentary Luke 12:2

"But there is nothing covered up, that shall not be revealed; and hid, that shall not be known." — Luke 12:2 (ASV)

Covered up (συγκεκαλυμμενον εστιν). Periphrastic perfect passive indicative of συγκαλυπτω, 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.
