Proverbs 17:7 "Excellent speech becometh not a fool: much less do lying lips a prince."
Just as lips of excellency are not fitting to a fool, even more so are lying lips not fitting for a ruler. Rather it is vice versa. Excellent speech is expected from a ruler, while lying is expected of a fool. Why are lying lips not becoming to a prince? Proverbs 16:12-13 say the throne is established by righteousness; therefore, for a king to commit wickedness, is abominable. Rather, lips that speak righteousness are the delight and love of kings.
The Hebrew word for "prince" also means, "willing heart, liberal" and was used to describe the people who willingly gave an offering to the Lord for the building of the tabernacle in Exodus 35:5, 22. This word indicates then, the stinginess of a fool, and the aspect of a good ruler or the generous being the servant of the people.
As Christians, who are kings and priests unto God according to Revelation 1:6 we have a duty to be truthful, compassionate, gentle, and yet bold in our speech. Our tongues must be yielded to the Lord. He is the only one that can tame it (James 3:8). Christ the King speaks only the truth. Are you delighting the King of heaven and earth by speaking what is right and true. Is your speech becoming of that of the child of the King, and of one who will one day reign with Him? Do you love righteousness and hate your own way, iniquity?
"But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:" Ephesians 4:15. Speaking the Truth in love is the key to spiritual growth. What has been excellent or superior about your speech today?
