'Rulers' in the Bible

“By me kings reignAnd rulers decide and decree justice.

Wisdom is too exalted for a [hardened, arrogant] fool;He does not open his mouth in the gate [where the city’s rulers sit in judgment].

When a land does wrong, it has many princes,But when the ruler is a man of understanding and knowledge, its stability endures.

It is not for kings, O Lemuel,It is not for kings to drink wine,Or for rulers to desire strong drink,
