Proverbs 16:13

¹¹ A just weight and balance are the LORD’s: all the weights of the bag are his work.

¹² It is an abomination to kings to commit wickedness: for the throne is established by righteousness.

Righteous lips are the delight of kings; and they love him that speaketh right.

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.

Do read the surrounding verses too, because the context often says more than a single verse.
