The Lord shall bring ... - The prophet having assured Ahaz that his kingdom should be free from the invasion that then threatened it, proceeds, however, to state to him that it would be endangered from another source.

Thy father's house - The royal family - the princes and nobles.

Days that have not come - Times of calamity that have not been equalled.

From the day that Ephraim departed from Judah - From the time of the separation of the ten tribes from the tribes of Judah and Benjamin.

Even the king of Assyria - This was done in the following manner. Though the siege which Rezin and Pekah had undertaken was not at this time successful, yet they returned the year after with stronger forces, and with counsels better concerted, and again besieged the city. This was in consequence of the continued and increasing wickedness of Ahaz; 2 Chronicles 28:1-5. In this expedition, a great multitude were taken captives, and carried to Damascus; 2 Chronicles 28:5. Pekah at this time also killed 120,000 of the Jews in one day 2 Chronicles 28:6; and Zichri, a valiant man of Ephraim, killed Maaseiah the son of Ahaz. At this time, also, Pekah took no less than 200,000 of the kingdom of Judah, proposing to take them to Samaria, but was prevented by the influence of the prophet Oded; 2 Chronicles 28:8-15. In this calamity, Ahaz stripped the temple of its treasures and ornaments, and sent them to Tiglath-pileser, king of Assyria, to induce him to come and defend him from the united arms of Syria and Ephraim. The consequence was, as might have been foreseen, that the king of Assyria took occasion, from this, to bring increasing calamities upon the kingdom of Ahaz. He first, indeed, killed Rezin, and took Damascus; 2 Kings 16:7.

Having subdued the kingdoms of Damascus and Ephraim, Tiglath-pileser became a more formidable enemy to Ahaz than both of them. His object was not to aid Ahaz, but to distress him 2 Chronicles 28:20; and his coming professedly and at the request of Ahaz, to his help, was a more formidable calamity than the threatened invasion of both Rezin and Pekah. God has power to punish a wicked nation in his own way. When they seek human aid, he can make this a scourge. He has kings and nations under his control; and though a wicked prince may seek earthly alliance, yet it is easy for God to allow such allies to indulge their ambition and love of rapine, and make them the very instruments of punishing the nation which they were called to defend. It should be observed that this phrase, 'even the king of Assyria,' is by many critics thought to be spurious, or a marginal reading, or gloss, that has by some means crept into the text. The ground of this opinion is, that it does not harmonize entirely with the following verse, where "Egypt" is mentioned as well as Assyria, and that it does not agree with the poetical form of the passage.

The Lord shall bring "But Jehovah will bring" - Houbigant reads וביא vaiyabi, from the Septuagint, αλλα επαξει ὁ Θεος, to mark the transition to a new subject.

Even the king of Assyria - Houbigant supposes these words to have been a marginal gloss, brought into the text by mistake; and so likewise Archbishop Secker. Besides their having no force or effect here, they do not join well in construction with the words preceding, as may be seen by the strange manner in which the ancient interpreters have taken them; and they very inelegantly forestall the mention of the king of Assyria, which comes in with great propriety in the 20th verse (Isaiah 7:20). I have therefore taken the liberty of omitting them in the translation.

The Lord shall bring upon thee,.... These words are directed to Ahaz; and show, that though he and his kingdom would be safe from the two kings that conspired against him, yet evils should come upon him from another quarter, even from the Assyrians he sent to for help, and in whom he trusted; in which the Lord himself would have a hand, and permit them in his providence, in order to chastise him for his unbelief, stubbornness, and ingratitude in refusing the sign offered him, and for his other sins; and the calamities threatened began in his time; and therefore it is said, "upon thee"; for Tilgathpilneser, king of Assyria, to whom he sent for help, instead of helping and strengthening him, distressed him, 2 Chronicles 28:20,

and upon thy people, and upon thy father's house; so in the reign of his son Hezekiah, Sennacherib, king of Assyria, invaded the land of Judah, took all its fenced cities, excepting Jerusalem, and came up even to that, 2 Kings 18:13 and in the times of Zedekiah, Nebuchadnezzar, king of Babylon, came up against Jerusalem, and destroyed it, and carried the people of Judah captive, 2 Kings 25:1 and these are the evil days, the days of affliction and adversity, here threatened:

days that have not come, from the day that Ephraim departed from Judah: meaning the revolt of the ten tribes from the house of David, in the times of Rehoboam, 1 Kings 12:16 which was a day of great adversity, a great affliction to the house of Judah; and there had been several evil days since, and that very lately; as when the king of Syria came into the land, and carried away great multitudes captives to Damascus; and when Pekah, king of Israel, slew in Judah, on one day, a hundred and twenty thousand valiant men, and carried captive two hundred thousand women, sons and daughters, with a great spoil, 2 Chronicles 28:5 and yet these were not to be compared with the calamitous times yet to come:

even the king of Assyria; or "with the king of Assyria", as the Vulgate Latin version renders it; rather the meaning is, that those days of trouble should come by the king of Assyria (i), as they did. The Septuagint version renders it, "from the day that Ephraim took away from Judah the king of the Assyrians"; and the Syriac and Arabic versions, just the reverse, "from the day that the king of the Assyrians", or "Assyria, carried away Ephraim from Judea"; neither of them right.

(i) "per regem Assyriae", Junius & Tremellius, Piscator; and which is preferred by Noldius, Ebr. Concord. Part. p. 120, No. 616.

The LORD shall bring upon thee, and upon thy people, and upon thy father's house, days that have not come, from the day that {p} Ephraim departed from Judah; even the king of {q} Assyria.

(p) Since the time that the twelve tribes rebelled under Rehoboam.

(q) In whom you have put your trust.

7:17 Shall bring - But altho' God will deliver you at this time, yet he will requite all your wickedness. Thee - For part of this Assyrian storm fell in Ahaz's reign. And - Upon thy sons and successors, the kings of Judah. Days - Calamities. Departed - When ten tribes revolted from thy father's house. The king - Who may well be called their plague or calamity, as he is called the rod of God's anger, chap.10:5.

Isa 7:17-25. Fatal Consequences of Ahaz' Assyrian Policy.

Though temporary deliverance (Isa 7:16; 8:4) was to be given then, and final deliverance through Messiah, sore punishment shall follow the former. After subduing Syria and Israel, the Assyrians shall encounter Egypt (2Ki 23:29), and Judah shall be the battlefield of both (Isa 7:18), and be made tributary to that very Assyria (2Ch 28:20; 2Ki 16:7, 8) now about to be called in as an ally (Isa 39:1-6). Egypt, too, should prove a fatal ally (Isa 36:6; 31:1, &c.).

7:17-25 Let those who will not believe the promises of God, expect to hear the alarms of his threatenings; for who can resist or escape his judgments? The Lord shall sweep all away; and whomsoever he employs in any service for him, he will pay. All speaks a sad change of the face of that pleasant land. But what melancholy change is there, which sin will not make with a people? Agriculture would cease. Sorrows of every kind will come upon all who neglect the great salvation. If we remain unfruitful under the means of grace, the Lord will say, Let no fruit grow on thee henceforth for ever.
