Isaiah 39:3

Then came Isaiah... — The words that follow, like those in Isaiah 7:3, are spoken with the authority at once of age and of a Divine mission, perhaps also of a master speaking to one who had been his pupil. No sooner does the arrival of the embassy from Babylon reach his ear than he goes straight to the king to ask him what it all meant. The king’s answer seems to plead that they came “from a far country” as an excuse. Could he refuse to admit those who had taken so long a journey in his honour? Could intercourse with a land so distant bring any moral or political danger? It was not like the alliance with Egypt, to which Isaiah was so strenuously opposed.
