Isaiah 31:4

And things of this kind would occur. "For thus hath Jehovah spoken to me, As the lion growls, and the young lion over its prey, against which a whole crowd of shepherds is called together; he is not alarmed at their cry, and does not surrender at their noise; so will Jehovah of hosts descend to the campaign against the mountain of Zion, and against their hill." There is no other passage in the book of Isaiah which sounds so Homeric as this (vid., Il. xviii. 161, 162, xii. 299ff.). It has been misunderstood by Knobel, Umbreit, Drechsler, and others, who suppose על לצבּא to refer to Jehovah's purpose to fight for Jerusalem: Jehovah, who would no more allow His city to be taken from Him, than a lion would give up a lamb that it had taken as its prey. But how could Jerusalem be compared to a lamb which a lion holds in its claws as tereph? (Isa 5:29). We may see, even from Isa 29:7, what construction is meant to be put upon על צבא. Those sinners and their protectors would first of all perish; for like a fierce indomitable lion would Jehovah advance against Jerusalem, and take it as His prey, without suffering Himself to be thwarted by the Judaeans and Egyptians, who set themselves in opposition to His army (The Assyrians).

The commentators have been misled by the fact, that a simile of a promising character follows immediately afterwards, without anything to connect the one with the other. But this abrupt μετάβασις was intended as a surprise, and was a true picture of the actual fulfilment of the prophecy; for in the moment of the greatest distress, when the actual existence of Jerusal…

This chapter is an abridgment of the foregoing chapter; the heads of it are much the same. Here is, I. A woe to those who, when the Assyrian army invaded them, trusted to the Egyptians, and not to God, for succour (Isa 31:1-3). II. Assurance given of the care God would take of Jerusalem in that time of danger and distress (Isa 31:4, Isa 31:5). III. A call to repentance and reformation (Isa 31:6, Isa 31:7). IV. A prediction of the fall of the Assyrian army, and the fright which the Assyrian king should thereby be put into (Isa 31:8, Isa 31:9).

31:4-9 This prophecy concerned God’s protection of Jerusalem and its rescue from the Assyrians.
