Isaiah 36:11
11Then Eliakim, Shebna and Joah said to Rabshakeh, “Please speak to your servants in Aramaic, for we understand it. Don’t speak to us in the Jews’ language in the hearing of the people who are on the wall.”
Wesley: he sends Rabshakeh, who by his blasphemous persuasions tempts Hezekiah to despair, and the people to revolt.
The officials ask Rabshakeh to speak Aramaic, the diplomatic language, so the people on the wall won’t understand. They fear the effect of his words on morale.
Calvin: this circumstance again shews how deeply Hezekiah was depressed, when by his ambassador he entreats so humbly the servant of his enemy. They request that he will not speak in this manner in the presence of the people; because it is difficult to restrain a people naturally giddy and fickle. These ambassadors therefore gain nothing from Rabshakeh; when he is entreated, he grows worse.
