In the days when Israel and Syria joined in league against Judah in the days of Ahaz. Via Isaiah and in the presence of his son Shear-Jashub (meaning: ‘a remnant shall return’) the Lord tells Ahaz not to fear, for the attack will not succeed, and Israel will no longer be a nation in 65 years’ time.
The Lord will give a sign: “…Behold a virgin shall conceive, and shall bear a son and shall call his name Immanuel.” (2 Nephi 17:14) Immanuel, meaning God with us. Before the child can distinguish good from evil (i.e. within a couple of years), he will be eating curds and honey (i.e. the land will be back to producing plenteous food), and both Israel and Syria will be defeated. However, the Assyrians (whom Judah called upon for help) will inflict heavy calamities upon Judah. Isaiah counsels against a Judah-Assyria alliance to counter the threat from the Israel-Syria one.
