Isaiah Calls Ahaz to Quiet Trust during the Coalition Crisis

Two northern kings come up, and Ahaz's heart shakes like trees in wind

It came to pass in the days of Ahaz the son of Jotham, the son of Uzziah, king of Judah, that Rezin the king of Syria, and Pekah the son of Remaliah, king of Israel, went up toward Jerusalem to war against it; but could not prevail. It was told the house of David, Syria is confederate with Ephraim. The heart of Ahaz and the heart of his people were moved as the trees of the wood are moved with the wind.

The crisis is the Syro-Ephraimite threat against Jerusalem in Ahaz's day. The unit is not a puzzle for date-setting later wars, and it is not a stage on which to skip to later Christology before the frightened king is addressed.

Isaiah takes Shear-jashub and offers a time-bounded promise

The LORD says to Isaiah, Go forth now to meet Ahaz, thou, and Shear-jashub thy son, at the end of the conduit of the upper pool in the highway of the fuller's field. Say, Take heed, and be quiet; fear not, neither be fainthearted for the two tails of these smoking firebrands. The conspiracy will not stand. Within sixty-five years Ephraim shall be broken, that it be not a people. If ye will not believe, surely ye shall not be established.

The son's name means a remnant shall return. The meeting place is a water installation, a royal anxiety site. Quiet trust is the political word: the coalition is nearly spent smoke. Faithless fear cannot establish the house of David. The symbolic child is a sign in this crisis, not a repeatable command to name children as oracles.
