'Teacher' in the Bible

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

"Futile! Futile!" laments the Teacher, "Absolutely futile! Everything is futile!"

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

The Teacher says: I discovered this while trying to discover the scheme of things, item by item.

"Absolutely futile!" laments the Teacher, "All of these things are futile!"

Not only was the Teacher wise, but he also taught knowledge to the people; he carefully evaluated and arranged many proverbs.

The Teacher sought to find delightful words, and to write accurately truthful sayings.
