Isaiah 8:12

A confederacy] alluding to the alliance between Israel and Syria, which caused so much fear in Judah (Isaiah 7:2). The same word is, however, elsewhere rendered 'conspiracy' or 'treason' (2 Kings 17:4; 2 Chronicles 23:13): so RV 'conspiracy' here. In that case the allusion would be to the cry of 'Conspiracy!' which, as some suppose, was raised against Isaiah and his followers by those in Judah who opposed the line of policy he advocated, and favoured Ahaz's project of alliance with Assyria. Similarly, the political opponents of Jeremiah attempted to discredit his teaching by accusing him of treachery against his country (Jeremiah 37:13).
