Charles Ellicott Commentary Isaiah 28:2

"Behold, the Lord hath a mighty and strong one; as a tempest of hail, a destroying storm, as a tempest of mighty waters overflowing, will he cast down to the earth with the hand." — Isaiah 28:2 (ASV)

The Lord has a mighty and strong one ... —The Hebrew may be either neuter, as in the Septuagint and Targum, or masculine, as in the Authorised Version. In either case it refers to the King of Assyria as the instrument of Jehovah’s vengeance, the comparisons employed to describe his action reproducing those of Isaiah 8:7-8; Isaiah 25:4. Here the picture is that of the “destroying storm,” the pestilent or blasting tempest withering, and the flood sweeping away, the beautiful “garland” of Samaria.
