John Calvin on Isaiah 36:9

9. And how dost thou despise? “How then wilt thou turn away?” — Eng. Ver. He confirms the preceding statement, and shews that ttezekiah is so far from being able to endure the presence of his king, that he ought not to be compared to the very smallest of his captains. In this insolent manner does he taunt him, that the Jews may not derive courage from the absence of Sennacherib, who was still detained by the siege of Lachish. Although, therefore, Sennacherib does not yet appear before them with his whole army, Rabshakeh boasts that his lieutenants are sufficiently powerful, so that Hezekiah ought not to hesitate to make submission.
