A divine sentence is in the lips of the king: his mouth transgresseth not in judgment.
A divine sentence (is) in the lips of the king. What a just and wise king (one worthy by of the high name and office) saith in pronouncing judgment, is sound and veracious, like a divinely oracular sentence. God gives him a kind of heaven-taught sagacity, (see an example, 1 Kings 3:16, etc.) This ought to be the aim of a king, to be just, true, and firm in judgment, as it he were speaking oracularly.
