Isaiah 28:21

It would be with them as it was with the Philistines when David turned their army into water at Baal-perazim (Sa2 5:20; Ch1 14:11), or when on another occasion he drove them before him from Gibeon to Gezer (Ch1 14:13.). "For Jehovah will rise up as in the mountain of Perazim, and be wroth as in the valley at Gibeon to work His work; astonishing is His work; and to act His act: strange is His act." The Targum wrongly supposes the first historical reminiscence to refer to the earthquake in the time of Uzziah, and the second to Joshua's victory over the Amorites. The allusion really is to the two shameful defeats which David inflicted upon the Philistines. There was a very good reason why victories over the Philistines especially should serve as similes. The same fate awaited the Philistines at the hands of the Assyrians, as predicted by the prophet in Isa 14:28. (cf., Isa 20:1-6). And the strangeness and verity of Jehovah's work were just this, that it would fare no better with the magnates of Judah at the hand of Asshur, than it had with the Philistines at the hand of David on both those occasions. The very same thing would now happen to the people of the house of David as formerly to its foes. Jehovah would have to act in opposition to His gracious purpose. He would have to act towards His own people as He once acted towards their foes. This was the most paradoxical thing of all that they would have to experience.

In this chapter, I. The Ephraimites are reproved and threatened for their pride and drunkenness, their security and sensuality (Isa 28:1-8). But, in the midst of this, here is a gracious promise of God's favour to the remnant of his people (Isa 28:5, Isa 28:6). II. They are likewise reproved and threatened for their dulness and stupidity, and unaptness to profit by the instructions which the prophets gave them in God's name (Isa 28:9-13). III. The rulers of Jerusalem are reproved and threatened for their insolent contempt of God's judgments, and setting them at defiance; and, after a gracious promise of Christ and his grace, they are made to know that the vain hopes of escaping the judgments of God with which they flattered themselves would certainly deceive them (Isa 28:14-22). IV. All this is confirmed by a comparison borrowed from the method which the husbandman takes with his ground and grain, according to which they must expect God would proceed with his people, whom he had lately called his threshing and the corn of his floor (Isa 21:10) (Isa 28:23-29). This is written for our admonition, and is profitable for reproof and warning to us.

28:21 as he did . . . at Mount Perazim: See 2 Sam 5:20. • God had rescued Israel through a hailstorm at Gibeon (Josh 10:10-12), but now he would turn against them.
