'Son' in the Bible

The following is a record of what Amos prophesied. He was one of the herdsmen from Tekoa. These prophecies about Israel were revealed to him during the time of King Uzziah of Judah and King Jeroboam son of Joash of Israel, two years before the earthquake.

I will turn your festivals into funerals, and all your songs into funeral dirges. I will make everyone wear funeral clothes and cause every head to be shaved bald. I will make you mourn as if you had lost your only son; when it ends it will indeed have been a bitter day.
