Proverbs 19:8

6 Many seek the favor of the prince, and everyone is a friend of the gift giver.

7 All the brothers of a poor man hate him— how much more do his friends avoid him! He may pursue them with pleading, but they are nowhere to be found.

He who acquires wisdom loves himself; one who safeguards understanding will find success.

9 A false witness will not go unpunished, and one who pours out lies will perish.

10 Luxury is unseemly for a fool— how much worse for a slave to rule over princes!

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