Other than the future? Possibly
If this is a reference to the Old Testament (OT) revelation being "veiled" OR the "mysteries" mentioned in the New Testament (NT) I will say the very purpose of the New Testament as a newer revelation was to reveal that which had previously been veiled or hidden AND the very purpose of revelation is revealing. It will be observed that most mentions of "mystery" in the NT come accompanied with the message they are now made known. The mystery of Christ is made known, for example. We now know something unknown in the OT: Christ crucified and resurrected. That is no longer veiled or hidden.
Is that along the lines of what you were asking, or is there something else?
