John Gill's Exposition of the Whole Bible
Isaiah 37:2
And he sent Eliakim, who was over the household, and Shebna the scribe,.... Two of the commissioners sent to Rabshakeh, and who heard his insolence and blasphemy, and were capable of giving a full account of it, to Isaiah the prophet:
and the elders of the priests; as the chief of those that were concerned in civil affairs, so the chief of those that were employed in sacred things, were sent: this was a very honourable embassy; and it was showing great respect to the prophet, to send such personages to him:
covered with sackcloth; as the king himself was, following his example; and this is to be understood not of the elders of the priests only, but of Eliakim and Shebna also. These, so clad, were sent by the king
unto Isaiah the prophet, the son of Amoz; to give him an account of the present situation of affairs, of the distress he was in, and to desire his prayers: a very proper person to apply to, a prophet, one highly dear to God, and honoured by him, had near access unto him, and knew much of his mind.
