In that eighth century B.C.E., Pekah and Rezin, the kings of Israel and Syria, were bent on overthrowing Ahaz, king of Judah, in order to put the son of Tabeel upon his throne. (Isa 7:1-6) Jehovah, however, remembered his kingdom covenant with David, the forefather of Ahaz, and sent his prophet with this reassuring message:

“Listen, please, O house of David. . . . Jehovah himself will give you men a sign: Look! The maiden herself will actually become pregnant, and she is giving birth to a son, and she will certainly call his name Immanuel. Butter and honey he will eat by the time that he knows how to reject the bad and choose the good. For before the boy will know how to reject the bad and choose the good, the ground of whose two kings you are feeling a sickening dread will be left entirely.”​—Isa 7:13-16.

Then, after telling about the birth of Isaiah’s second son, Maher-shalal-hash-baz, the prophecy next describes how the threat to Judah would be removed. As an irresistible flood, the Assyrians would completely inundate Syria and the northern kingdom of Israel, not stopping until they had dangerously spread over the land of Judah, even “to fill the breadth of your land, O Immanuel!”

“Before the boy will know how to call out, ‘My father!’ and ‘My mother!’ one will carry away the resources of Damascus and the spoil of Samaria before the king of Assyria.” (Isa 8:1-4) Certainly this echoes what was said about Immanuel: “Before the boy will know how to reject the bad and choose the good, the ground of whose two kings [of Damascus and Samaria] you are feeling a sickening dread will be left entirely.” (Isa 7:16)
