This shows that in a well-ordered court and government smiles and favours are dispensed among those that are employed in public trusts according to their merits; Solomon lets them know he will go by that rule, 1.
That those who behave themselves wisely shall be respected and preferred, whatever enemies they may have that seek to undermine them. No man's services shall be neglected to please a party or a favourite.
2. That those who are selfish and false, who betray their country, oppress the poor, and sow discord, and thus cause shame, shall be displaced and banished the court, whatever friends they may make to speak for them.
