'Ruler' in the Bible

Which having no chief, Overseer, or ruler,

When thou sittest to eat with a ruler, Consider diligently him that is before thee;

By long forbearing is a ruler persuaded, And a soft tongue breaketh the bone.

As a roaring lion, and a ranging bear,'so is a wicked ruler over a poor people.

If a ruler hearkeneth to falsehood, All his servants are wicked.

Many seek the ruler's favor; But a man's judgment cometh from Jehovah.
