We may hence learn these lessons: - 1. That, while princes and counsellors have public matters under debate, it is not fair to appeal to the people. It was a reasonable motion which Hezekiah's plenipotentiaries made, that this parley should be held in a language which the people did not understand (Isa 36:11), because reasons of state are secret things and ought to be kept secret, the vulgar being incompetent judges of them. It is therefore an unfair practice, and not doing as men would be done by, to incense subjects against their rulers by base insinuations. 2. Proud and haughty scorners, the fairer they are spoken to, commonly speak the fouler. Nothing could be said more mildly and respectfully than that which Hezekiah's agents said to Rabshakeh. Besides that the thing itself was just which they desired, they called themselves his servants, they petitioned for it: Speak, we pray thee; but this made him the more spiteful and imperious. To give rough answers to those who give us soft answers is one way of rendering evil for good; and those are wicked indeed, and it is to be feared incurable, with whom that which usually turns away wrath does but make bad worse. 3. When Satan would tempt men from trusting in God, and cleaving to him, he does so by insinuating that in yielding to him they may better their condition; but it is a false suggestion, and grossly absurd, and therefore to be rejected with the utmost abhorrence. When the world and the flesh say to us, "Make an agreement with us and come out to us, submit to our dominion and come into our interests, and you shall eat every one of his own vine," they do but deceive us, promising liberty when they would lead us into the basest captivity and slavery. One might as well take Rabshakeh's word as theirs for kind usage and fair quarter; therefore, when they speak fair, believe them not. Let them say what they will, there is no land like the land of promise, the holy land. 4. Nothing can be more absurd in itself, nor a greater affront to the true and living God, than to compare him with the gods of the heathen; as if he could do no more for the protection of his worshippers than they can for the protection of theirs, and as if the God of Israel could as easily be mastered as the gods of Hamath and Arphad, whereas they are vanity and a lie. They are nothing; he is the great I AM: they are the creatures of men's fancy and the works of men's hands; he is the Creator of all things. 5. Presumptuous sinners are ready to think that, because they have been too hard for their fellow-creatures, they are therefore a match for their Creator. This and the other nation they have subdued, and therefore the Lord himself shall not deliver Jerusalem out of their hand. But, though the potsherds may strive with the potsherds of the earth, let them not strive with the potter. 6. It is sometimes prudent not to answer a fool according to his folly. Hezekiah's command was, "Answer him not; it will but provoke him to rail and blaspheme yet more and more; leave it to God to stop his mouth, for you cannot." They had reason enough on their side, but it would be hard to speak it to such an unreasonable adversary without a mixture of passion; and, if they should fall a railing like him, Rabshakeh would be much too hard for them at that weapon. 7. It becomes the people of God to lay to heart the dishonour done to God by the blasphemies of wicked men, though they do not think it prudent to reply to those blasphemies. Though they answered him not a word, yet they rent their clothes, in a holy zeal for the glory of God's name and a holy indignation at the contempt put upon it. They tore their garments when they heard blasphemy, as taking no pleasure in their own ornaments when God's honour suffered.

Neither let Hezekiah make you trust in the Lord,.... Hezekiah trusted in the Lord himself, and he endeavoured, both by his own example, and by arguments, to persuade his people to do so likewise; of this Rabshakeh was sensible, and was more afraid of this than of any thing else, and, therefore laboured this point more than any other; see Ch2 32:6;

saying, the Lord will surely deliver us, this city shall not be delivered into the hand of the king of Assyria: which he might say with the greatest confidence, since the Lord had promised to defend it, Isa 31:5 and especially if his sickness, and recovery out of it, and promises then made to him, were before this, as some think; since it is expressly promised by the Lord, that he would deliver him and the city out of the hand of the king of Assyria, Isa 38:6.

The foes of God's people cannot succeed against them, unless they can shake their trust in Him (compare Isa 36:10).
