Matthew Henry and continuators on Proverbs 16:14-15

14 The wrath of a king is as messengers of death: but a wise man will pacify it. 15 In the light of the king's countenance is life; and his favour is as a cloud of the latter rain.

These two verses show the power of kings, which is every where great, but was especially so in those eastern countries, where they were absolute and arbitrary. Whom they would they slew and whom they would they kept alive. Their will was a law. We have reason to bless God for the happy constitution of the government we live under, which maintains the prerogative of the prince without any injury to the liberty of the subject. But here it is intimated, 1. How formidable the wrath of a king is: It is as messengers of death; the wrath of Ahasuerus was so to Haman. An angry word from an incensed prince has been to many a messenger of death, and has struck so great a terror upon some as if a sentence of death had been pronounced upon them. He must be a very wise man that knows how to pacify the wrath of a king with a word fitly spoken, as Jonathan once pacified his father's rage against David, 1 Sam. xix. 6. A prudent subject may sometimes suggest that to an angry prince which will cool his resentments. 2. How valuable and desirable the king's favour is to those that have incurred his displeasure; it is life from the dead if the king be reconciled to them. To others it is as a cloud of the latter rain, very refreshing to the ground. Solomon put his subjects in mind of this, that they might not do any thing to incur his wrath, but be careful to recommend themselves to his favour. We ought by it to be put in mind how much we are concerned to escape the wrath and obtain the favour of the King of kings. His frowns are worse than death, and his favour is better than life; and therefore those are fools who to escape the wrath, and obtain the favour, of an earthly prince, will throw themselves out of God's favour, and make themselves obnoxious to his wrath.
