'Son' in the Bible

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

There is a person without a companion, without even a son or brother, and though there is no end to all his struggles, his eyes are still not content with riches. “So who am I struggling for,” he asks, “and depriving myself from good?” This too is futile and a miserable task.

But those riches perish by evil travail: and he begetteth a son, and there is nothing in his hand.

Blessed art thou, O land, when thy king is the son of nobles, and thy princes eat in due season, for strength, and not for drunkenness!

And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.
