Isaiah names a son Maher-shalal-hash-baz — "speed the spoil, hasten the prey" — as a living sign that Damascus and Samaria fall before Assyria's king. The chapter pivots on Judah's refusal of the soft waters of Shiloah (Jehovah's quiet kingship) for the louder waters of political confederacy; the Lord answers by bringing the river of Assyria up to the neck of the land of Immanuel. Then the deeper instruction: do not call confederacy what the people call confederacy. Sanctify Jehovah Himself as fear and sanctuary — and He becomes a stone of stumbling to both houses of Israel. The testimony is bound, the law sealed among disciples, the prophet and his children left as signs in a land driven to darkness. The sealed-up word among a remnant is the pattern.
