“A Prophecy Against the Philistines,” Isaiah 14:28) In the year that king Ahaz died was this burden. 29) Rejoice not thou, whole Palestina, because the rod of him that smote thee is broken: for out of the serpent’s root shall come forth a cockatice (or, snake), and his fruit shall be a fiery flying serpent. 30) And the firstborn of the poor shall feed, and the needy shall lie down in safety: And I Will Kill thy root with famine, and he shall slay thy remnant (or, survivors). 31) Howl, O gate; cry, O city; thou, whole Palestina, art dissolved: for there shall come from the north a Smoke, and none shall be alone in his appointed times (or, assemblies). 32) What shall one then answer the messengers of the nation? That The Lord Hath Founded Zion, and the poor of His People Shall Trust In It.
Nelson’s Compact Bible Commentary – v26-28, King Ahaz died in 720 B. C. v29, Rod is probably a metaphor for the Assyrian king (10:5). it’s offspring will be … serpent: More trouble would come upon Philistia; it would have nothing for which to rejoice. v30, Like Babylon (v. 22) —but unlike Israel—Philistia would have no future, because it would have no remnant. v31, The gate of a walled city was its weakest point. When the gate fell, the city could be taken. No one will be alone, speaks of the close ranks of the Assyrian army. v32, founded Zion: The destruction of Philistia would leave no refuge for the Philistines.

Matthew Henry’s Concise Bible Commentary – v28 – v32, Assurance is given of the destruction of the Philistines and their power, by famine and war. Hezekiah would be more terrible to them than Uzziah had been. Instead of rejoicing, there would be lamentation (wailing, crying), for the whole land would be ruined. Such destruction will come upon the proud and rebellious, but The Lord Founded Zion For A Refuge To Poor Sinners, Who Flee From The Wrath To Come, (by turning from their sinfulness) and Trust(ing) In His Mercy Through Christ Jesus. Let us tell all around, of our comfort and security, And Exhort Them To Seek The Same Refuge and Salvation.
