Charles Ellicott Commentary Matthew 10:26

"Fear them not therefore: for there is nothing covered, that shall not be revealed; and hid, that shall not be known." — Matthew 10:26 (ASV)

Fear them not therefore: for... The words that command them to banish fear look both backward and forward. Why should they be afraid when they are only suffering what their Master Himself suffered, and when they can look forward to the public declaration of His triumph? In that day, the veil that now conceals the truth will be drawn away. The unknown sufferers for the truth will receive the crown of martyrdom, and the undetected cowardice that shrinks from confessing Christ will then be laid bare.
