Behold, the Lord hath a mighty and strong one, which as a tempest of hail and a destroying storm, as a flood of mighty waters overflowing, shall cast down to the earth with the hand.
Strong one - the Assyrian (Isaiah 10:5).
(Which) as a tempest ... shall cast down to the earth - namely, Ephraim (Isaiah 28:1), and Samaria its crown.
With the hand - with a mighty hand: implying the ease and irresistible power with which Yahweh acts (Isaiah 8:11; Ezekiel 20:33; Daniel 9:15).
