And he shall pass through Judah; he shall overflow and go over, he shall reach even to the neck; and the stretching out of his wings shall fill the breadth of thy land, O Immanuel.
And he shall pass through Judah,.... That is, the king of Assyria, compared to a river of mighty waters; who should not only run over and possess the land of Israel, or the ten tribes, but should enter into Judea, and pass through it, as a chastisement for not trusting in the Lord, but sending to Assyria for help; who instead of helping, distressed them in the times of Ahaz, even Tilgathpilneser king of Assyria, 2 Chronicles 28:20:
he shall overflow, and go over; the whole land of Judea, as Sennacherib king of Assyria did in Hezekiah's time:
he shall reach even to the neck; that is, to Jerusalem: the whole land is compared to a body, of which Jerusalem was the head; the Assyrian army, comparable to the waters of a great river, overflowed the whole land, took all the fenced cities of Judah, and came up even to Jerusalem, so that the whole was in great danger of being drowned and destroyed; as a man is, when the waters are come up to his neck; see 2 Kings 18:13:
and the stretching out of his wings, the wings of the Assyrian army,
shall fill the breadth of thy land, O Immanuel; Judea, called Immanuel's land, because he was to be born there, and converse and die there; and this is particularly mentioned, to show that, though this land should be overrun by the Assyrians, yet not destroyed, until Immanuel, the son of the virgin, was born here. The Targum is,
"and he shall pass through the land of the house of Judah as an overflowing torrent, unto Jerusalem shall he come; and the people of his army shall fill the breadth of thy land, O Immanuel.''
