Adam Clarke on Daniel 10:10

A hand touched me - Nothing was apparent or palpable but a hand. A hand had written Belshazzar's fate upon the wall; and the hand is frequently mentioned when the power or majesty of God is intended. Perhaps by hand God himself may be meant. It is remarkable that in a very ancient MS. of the Septuagint, more than a thousand years old, now in the imperial library of Vienna, adorned with paintings which have been engraved for the catalogue of Lambechius, and transferred to that of Nesselius, all the appearances of God are represented by a hand in the clouds.
