Charles Ellicott Commentary Isaiah 21:8

"And he cried as a lion: O Lord, I stand continually upon the watch-tower in the day-time, and am set in my ward whole nights;" — Isaiah 21:8 (ASV)

And he cried, A lion. —Better, As a lion. The cry seems to be the low murmur of the eager, almost angry, impatience by which the prophet or the ideal watchman was stirred.
