This is to the same purport with what we had Pro 16:14, Pro 16:15, and the design of it is, 1. To make kings wise and considerate in dispensing their frowns and smiles. They are not like those of common persons; their frowns are very terrible and their smiles very comfortable, and therefore it concerns them to be very careful that they never frighten a good man from doing well with their frowns, nor ever give countenance to a wicked man in doing ill with their smiles, for then they abuse their influence, Rom 13:3. 2. To make subjects faithful and dutiful to their princes. Let them be restrained from all disloyalty by the consideration of the dreadful consequence of having the government against them; and let them be encouraged in all good services to the public by the hopes of the favour of their prince. Christ is a King whose wrath against his enemies will be as the roaring of a lion (Rev 10:3) and his favour to his own people as the refreshing dew, Psa 72:6.
