Isaiah 7:17
17 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 Ephraim departed from Judah; even the king of Assyria.
Isa. 7:17. "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 Ephraim departed from Judah, even the king of Assyria." This seems not to be spoken of the king of Israel mentioned in the foregoing verse, but of Ahaz the king of Judah, to whom the prophet was then speaking. It could not be meant of Pekah, the king of Israel, because it speaks of bringing the king of Assyria in his father's house, but the family of Pekah was not cut off by the king of Assyria, but by Hoshea the son of Elah, who conspired against him, and slew him, and reigned in his stead. 2 Kings 15:30. God by the prophet had offered great encouragement to Ahaz under his present distress and fear of Pekah and Rezin, and gave him a glorious sign, which he would not give heed to, as appears by verse 12. His confidence was not in God for help, but in the king of Assyria, whom he had hired by the treasures of both church and state, and by basely promising to be his servant. 2 Kings 16:7; 2 Kings 16:8. Seeing he would not believe God's promises, nor take encouragement from his signs, therefore he should not be established; and though God would do great things for his people by the Immanuel, that should be born in his family, yet he should have no benefit of it; and though it was true as the prophet had told him, that he should not be hurt by the kingdom of Syria, and kingdom of Ephraim, that was now plotting his ruin; yet seeing he would not believe, he should not be the better for it, for their should come a greater calamity upon him, than ever the kingdom of Judah suffered from the kingdom of Israel, and indeed greater than ever they suffered since the kingdoms were divided from them, and became unfriendly to them; and that from the king of Assyria himself, whom he trusted so much in for help, against the kingdom of Israel. The calamity came upon him in his life-time in a measure, as it is said in this verse [upon thee ;] for when the king of Assyria came up he distressed him, and strengthened him not; 2 Chronicles 28:20; 2 Chronicles 28:21; and afterwards it came upon his father's house, and on his people.
Isa. 8:7-8
