The old testament YHWH assured Isaiah of a great many things, and used Isaiah's child's birth to mark a few events, too. Isaiah is said to have married a Prophetess.
He was assuring Isaiah a wrong would be righted, just after the birth of the child, a wrong to a nation would be restored, the fat of that particular nation's land, though God had no covenant with that particular nation in question, he righted a wrong, foretold their restoration.
same chapter:
"Now therefore, behold, the Lord bringeth up upon them the waters of the river, strong and many, even the king of Assyria, and all his glory: and he shall come up over all his channels, and go over all his banks:
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."
There was another more vulgar proverb of the man being "in it up to his neck", and that acting, not to perturb him or make him vomit, but as a protective shell from yet worse things, like the mouse that the cow plopped into a pile of poop. It was protective, and a small curse turned out to be a big blessing in the long run.
