'King' in the Bible

The words of the Teacher, the son of David, king in Jerusalem.

I, the Teacher, have been king over Israel in Jerusalem.

Next I turned to examine wisdom, insanity, and foolishness, because what can a person do who succeeds the king except what has already been accomplished?

A poor but wise youth is better than an old but foolish king who will no longer accept correction.

Also, the increase of the land belongs to everyone; the king himself is served by his field.

I advise doing what the king says, especially regarding an oath to God.

There was a little city with few men in it. A great king came against it, surrounded it, and built massive siege ramps against it.

Woe to the land whose king is a youth and whose princes feast in the morning.

That land is blessed whose king is of noble birth, whose princes feast at the right time, for strength, and not to become drunk.

Do not curse the king, even in your thoughts. Do not curse the rich, even in your bedroom. For a bird will fly by and tell what you say, or something with wings may talk about it.
